Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Application Serial No. 63 / 317,670, filed on March 8, 2022, entitled “SOLID-STATE POWERCONTROLLER WITH TRANSFORMER SOFT-START,” with John Van Fossen as the inventor, under 35 U.S.C. §119(e), which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to systems and methods for power control, and more particularly, to dynamic solid-state power control. Background Art

[0004] Dynamic load control in high power applications remains a key challenge, particularly for applications requiring high reliability power, such as, but not limited to, data centers. For example, energizing a power transformer in response to a cold start condition typically results in an initial burst of current that may be higher than the nominal power rating of the transformer, which may result in wear on the power transformer itself as well as any connected loads. Therefore, it is desirable to develop systems and methods for addressing the above-mentioned deficiencies. Summary of the invention

[0005] A power distribution system is disclosed herein. In some embodiments, the power distribution system includes two or more solid-state power controllers (SSPCs) for regulating power between an input power source and two or more loads, wherein each of the two or more SSPCs is configured to be coupled to a different load of the two or more loads. The system may also include a controller for receiving performance specifications of the two or more loads, receiving operating conditions of at least one of any of the two or more loads or the input power source as feedback data, and directing the two or more SSPCs to disconnect or connect any of the two or more loads from the input power source based on the feedback data to achieve the performance specifications of the two or more loads.

[0006] A power distribution method is disclosed herein. The method may include: receiving performance specifications of two or more loads; receiving feedback data from at least one of any load of the two or more loads or an input power source; and directing two or more SSPCs to disconnect or connect any load of the two or more loads from the input power source based on the feedback data to achieve the performance specifications of the two or more loads. In some embodiments, each of the two or more SSPCs is coupled to a different load of the two or more loads.

[0007] The systems and methods disclosed herein may operate based on any type or combination of performance specifications known in the art, including, but not limited to, uptime specifications, reliability specifications, billing specifications, or cost specifications. In addition, different SSPCs within a power distribution system may provide different performance specifications to attached loads, and power distribution to various loads may be prioritized. As an illustration, the power distribution system disclosed herein may dynamically disconnect and reconnect loads with lower priority as needed to ensure performance of higher priority loads.

[0008] In some embodiments, the power distribution system also provides voltage control when disconnecting or connecting a load including a power transformer (e.g., soft start) to mitigate or eliminate inrush current. In this way, the power distribution system disclosed herein can provide scalable dynamic power control for demanding high-power applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Reference will now be made in detail to the disclosed subject matter, which is illustrated in the accompanying drawings. The present disclosure has been particularly illustrated and described with respect to certain embodiments and specific features thereof. The embodiments set forth herein are considered to be illustrative rather than restrictive. It should be readily apparent to one of ordinary skill in the art that various changes and modifications may be made in form and detail without departing from the spirit and scope of the present disclosure.

[0015] Embodiments of the present disclosure relate to systems and methods for dynamic power management in high power and / or high reliability systems using solid state power controllers (SSPCs), wherein the SSPCs are connected to various loads to enable rapid connection or disconnection of any of the various loads to an input power source or input power network. Additional embodiments of the present disclosure relate to utilizing SSPCs to manage connection and disconnection of loads to minimize wear. For example, some embodiments relate to solid state power controls with soft start capability to provide dynamic control of loads including, but not limited to, power transformers while mitigating or eliminating inrush current to provide high operational reliability and product life.

[0016] It is contemplated herein that dynamic load control may be useful in a variety of applications. As a non-limiting illustration, a power distribution system may sell or provide power with performance specifications, such as, but not limited to, specifications for reliability or uptime. For example, power uptime may be specified by a number of 9s, such that 3 9s corresponds to 99.9% uptime, 5 9s corresponds to 99.999% uptime, and so on. To meet these uptime levels, the power distribution system may provide excess capacity to provide power in the event of a primary input power failure. However, as uptime requirements increase, this excess capacity may become considerable, such that it may be desirable for the power distribution system to provide power at different uptime levels. In this manner, the power distribution system may selectively disconnect and reconnect loads to ensure a specified uptime for all available loads. As an illustration, such a power distribution system may selectively disconnect one or more loads specified at a lower uptime level (e.g., 3 9s) as needed to ensure operation of loads at a higher uptime level (e.g., 5 9s), based on, for example, but not limited to, operational requirements of increased load demand at a higher uptime level or decreased performance of the input power network. As another non-limiting illustration, reliability may be specified by a metric such as, but not limited to, mean time between failures. As another non-limiting illustration, a distribution system may sell or provide electricity at different billing specifications or cost specifications. For example, certain loads may be subject to a fixed resource allocation (e.g., fixed on-time, fixed electricity cost, etc.) and be disconnected when the resource allocation is met, and then may be reconnected when appropriate. In another example, certain electricity may be sold or provided in grades to allow for reduced uptime requirements or complete disconnection during times of peak energy usage in exchange for cost savings. The distribution system may then selectively disconnect and connect such loads as needed to balance various performance specifications.

[0017] In some embodiments, the power distribution system includes one or more SSPCs connected to an input power network, wherein each SSPC is also connected to at least one load. In this manner, the SSPC can dynamically connect or disconnect the associated load from the input power network in a controlled manner (e.g., using soft start techniques). The power distribution system may additionally include a controller coupled to the SSPC to provide control over various aspects of the operation of the SSPC, such as, but not limited to, connecting the load to the input power network, disconnecting the load from the power network, or analyzing feedback from connected components. In some embodiments, the controller also provides remote operation of the power distribution system.

[0018] It is also contemplated herein that rapid connection and disconnection to an input power source presents various challenges, particularly when a load is powered through a power transformer. In particular, rapid voltage changes may cause large inrush currents, which may cause wear on both the power transformer and the connected load. Accordingly, a power distribution system including a SSPC may use a controlled voltage profile to connect and / or disconnect loads to mitigate and, in some cases, eliminate such inrush currents.

[0019] Now refer to Figures 1 to 2B , according to one or more embodiments of the present disclosure, systems and methods for power distribution are described in more detail.

[0020] Figure 1 is a block diagram illustration of a power distribution system 100 according to one or more embodiments of the present disclosure.

[0021] In some embodiments, the power distribution system 100 includes two or more SSPCs 102 for conditioning power from an input power source 104 to two or more loads 106, wherein each SSPC 102 can be configured to be connected to one of the two or more loads 106. For example, Figure 1 A power distribution system 100 is shown that includes three SSPCs 102 to provide dynamic control of three loads 106. In addition, it should be understood that any particular load 106 may be associated with a single load device (e.g., a single piece of equipment) or multiple load devices. For example, multiple load devices may be jointly powered by a power distribution unit (PDU) connected between the load devices and the associated SSPCs 102.

[0022] The SSPC 102 may include any number or type of solid-state switching devices 108 and associated circuitry suitable for regulating power from the input power source 104 to the attached load 106, such as, but not limited to, silicon-controlled rectifiers (SCRs) or insulated gate bipolar transistors (IGBTs). For example, the SSPC 102 may include pairs of solid-state switching devices 108 in a full-wave power bridge configuration. Furthermore, the SSPC 102 may include additional elements, such as, but not limited to, snubber circuits, preload circuits, etc.

[0023] In some embodiments, the power distribution system 100 also includes one or more controllers 110 communicatively coupled to at least the SSPC 102. In this manner, the controller 110 can direct the operation of the SSPC 102 (e.g., via control signals) and, therefore, direct the flow of power from the input power source 104 to the various loads 106. The controller 110 may include any number of processors or processing elements known in the art. For example, the controller 110 may include one or more processing or logic elements, such as, but not limited to, one or more microprocessor devices, one or more digital signal processors (DSPs), one or more field programmable gate arrays (FPGAs), one or more complex programmable logic devices (CPLDs), or one or more application specific integrated circuit (ASIC) devices. The controller 110 may also include one or more memory devices. The memory device may also include any storage medium known in the art suitable for storing program instructions executable by an associated processor, such as, for example, a non-transitory storage medium including, but not limited to, a read-only memory (ROM) or a random access memory (RAM). In this manner, the processor may execute program instructions stored on the storage medium.

[0024] In some embodiments, the controller 110 includes various components suitable for driving one or more SSPCs 102 or components therein. For example, the controller 110 may include a gate drive circuit system 112 (e.g., a gate driver) for driving the solid-state switching device 108 in the SSPC 102. As another example, the controller 110 may include a drive controller 114 (e.g., a DSP or other processing device) for generating drive signals for the gate drive circuit system 112. In this manner, the drive controller 114 can control the operation of the solid-state switching device 108 through the gate drive circuit system 112 based on operational needs. The gate drive circuit system 112 may include any number or type of components suitable for accepting drive signals (e.g., logic signals, etc.) from the controller 110 and providing the necessary current or voltage to control the operation of the solid-state switching device 108 of the SSPC 102. By way of illustration, the gate drive circuit system 112 may include, but is not limited to, a low-side driver, a high-side / low-side driver, a single-channel driver, a half-bridge driver, a three-phase driver, and the like. In some embodiments, the gate drive circuitry 112 and / or the drive controller 114 are configured to provide controlled connection and / or disconnection of the load 106. For example, the gate drive circuitry 112 and / or the drive controller 114 can be configured to implement a soft start when powering the load 106 with the power transformer to mitigate or eliminate inrush current.

[0025] It is contemplated herein that one or more controllers 110 may be distributed among or integrated with any number of components of the power distribution system 100, including, but not limited to, any of the SSPCs 102. In this manner, any descriptions herein depicting components of the controller 110 are provided for illustrative purposes only and should not be construed as limiting. For example, the power distribution system 100 may include a single controller 110 for driving any number of SSPCs 102. As another example, the controller 110 (or a portion thereof) may be integrated with any of the SSPCs 102 of the power distribution system 100. As another example, various control aspects may be distributed. For example, the power distribution system 100 may include a master controller 110 coupled to the SSPCs 102 to control power flow to various loads 106 (e.g., to ensure operation of the loads 106 under specified performance specifications), wherein each SSPC 102 includes an internal controller 110 having a gate drive circuit system 112 and an associated drive controller 114.

[0026] In some embodiments, one or more controllers 110 include a human-machine interface (HMI) 116 and / or may be configured for remote operation via a communication circuit system 118. For example, the HMI 116 may include a display for displaying data of the power distribution system 100 (e.g., data associated with an operating state or a load condition (e.g., high, low, abnormal, etc.). The display of the HMI 116 may include any display known in the art. For example, the display may include, but is not limited to, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED)-based display, or a CRT display. Those skilled in the art will recognize that any display device capable of being integrated with the HMI 116 is suitable for implementation in the present disclosure. As another example, the HMI 116 may include an input device for receiving selections and / or instructions from a user, such as, but not limited to, a keyboard, a mouse, or a touch screen interface.

[0027] In some embodiments, the power distribution system 100 controls power to one or more loads 106 based at least in part on feedback from components such as, but not limited to, the input power source 104 or the connection of one or more loads 106. For example, the feedback may include operating conditions of the load 106, such as, but not limited to, past load conditions, current load conditions, or expected load conditions. As another example, the feedback may include operating conditions of the input power source 104, such as, but not limited to, past power supply conditions, current power supply conditions, or expected power supply conditions. Such feedback may be generated from the HMI 116 by a monitoring circuit system (e.g., a voltage monitoring circuit system, a current monitoring circuit system, etc.) within the power distribution system 100, or received from an external system (e.g., the input power source 104, the load 106, an external monitoring circuit system, etc.). In this way, the power distribution system 100 can selectively connect or disconnect any of the loads 106 as needed based on dynamically changing conditions from any of the input power source 104 and / or the load 106 to meet performance specifications.

[0028] Now refer to Figure 2A and Figure 2B It is contemplated herein that the SSPC 102 may be configured for single-phase or multi-phase operation.

[0029] Figure 2Ais a conceptual schematic diagram of an SSPC 102 suitable for 1-phase operation according to one or more embodiments of the present disclosure. In this configuration, the SSPC 102 may include an input power terminal 202 (labeled here as 1P) and an input neutral terminal 204 for receiving input power from an input power source 104. In some embodiments, the SSPC 102 may include a solid-state switch device 108 connected to the input power terminal 202 to regulate power to the output power terminal 206 relative to the output neutral terminal 208. Figure 2A Also shown is a preload circuit 210 between the output power terminal 206 and the output neutral terminal 208 .

[0030] Figure 2B 1 is a conceptual schematic diagram of an SSPC 102 suitable for 3-phase operation according to one or more embodiments of the present disclosure. In this configuration, the SSPC 102 may include three input power terminals 202 (labeled here as A, B, and C) for 3-phase power and three output power terminals 206. In some embodiments, as shown in FIG. Figure 2B As shown, the SSPC 102 includes a solid-state switch device 108 for each phase. In some embodiments, although not shown, the SSPC 102 may also include a solid-state switch device 108 on the neutral line (eg, between the input neutral terminal 204 and the output neutral terminal 208).

[0031] Usually refer to Figure 2A and Figure 2B , it should be understood that Figure 2A and Figure 2B and the associated descriptions are provided for illustrative purposes only and should not be construed as limiting. For example, Figure 2A and Figure 2B Various aspects of the controller 110 are shown integrated within the SSPC 102. However, as previously described herein, such components (or portions thereof) may also be provided external to any particular SSPC 102.

[0032] In addition, it is contemplated herein that the input power source 104 may generally include any number of input power sources, such as, but not limited to, utility connections, generators, uninterruptible power supplies (UPS), and the like. For example, the input power source 104 may include at least one primary power source and at least one backup power source for providing power in the event that the primary power source fails or is otherwise degraded. In such a configuration, the input power source 104 may also include, but need not include, various solid-state power control components to selectively control which input power source is directed to the power distribution system 100. The use of SSPCs to switch between available input sources to supply power to a load is generally described in U.S. Patent No. 11,171,508, issued on November 9, 2021, U.S. Patent No. 10,903,649, issued on January 26, 2021, and International Patent Publication No. WO2014 / 158065, published on October 2, 2014, all of which are incorporated herein by reference in their entirety.

[0033] Now usually refer to Figures 1 to 2B , according to one or more embodiments of the present disclosure, various implementations of the power distribution system 100 are described in more detail.

[0034] It is contemplated herein that the power distribution system 100 facilitates dynamic power control of various loads 106 and can be suitable for a wide variety of applications. In addition, the use of the SSPC 102 for load control enables soft starting of the load 106 coupled to the power transformer so that the power distribution system 100 can provide excellent performance and reliability even under high power operation. In particular, the solid-state switch device 108 as disclosed herein can be particularly well suited for, but not limited to, applications in which the load 106 is dynamically connected to and / or disconnected from the input power source 104.

[0035] In some embodiments, different SSPCs 102 may provide different performance specifications to attached loads 106, where the performance specifications may include, but are not limited to, uptime specifications, reliability specifications, billing specifications, or cost specifications. In such a configuration, the power distribution system 100 may prioritize the operation of the loads 106 (e.g., via the SSPCs 102) based on the performance specifications. As an illustration, the power distribution system 100 may be configured to provide a first performance specification of five nines uptime (99.999% uptime) to a first load 106 connected to a first SSPC 102, and to provide a second performance specification of three nines uptime (99.9% uptime) to a second load 106 connected to a second SSPC 102 (e.g., the performance specification of the first SSPC 106 is more stringent than the performance specification of the second SSPC 106). In this configuration, the power distribution system 100 may selectively disconnect (e.g., switch off) the loads 106 as needed to ensure that the first SSPC 102 continues to achieve its performance specifications. For example, if the capacity of the input power source 104 is insufficient to provide sufficient power to both the first load 106 and the second load 106 due to any reason such as, but not limited to, an increase in demand from the first load 106 or a decrease in the performance of the input power source 104, it may be necessary to disconnect the load 106 attached to the second SSPC 102. In addition, when the capacity of the input power source 104 is sufficient to power both the first load 106 and the second load 106, the power distribution system 100 may reconnect the second load 106.

[0036] The method can be extended to any number of performance specifications. As another illustration, the distribution system can sell or provide electricity at different billing specifications or cost specifications. In this way, the distribution system 100 can selectively disconnect or connect various loads to ensure that the reliability specifications of each load are met. As another illustration, the billing specification can be associated with the resource allocation of one or more loads 106. In this configuration, the distribution system 100 can selectively disconnect various loads 106 when the assigned resource allocation is met, and reconnect the load 106 when the assigned resource allocation is modified. As another illustration, the cost specification can be attributed to one or more loads 106 that provide guidelines for cost saving measures (e.g., based on customer consent). For example, the cost specification can stipulate that a specific load 106 can be turned off during peak power usage time or can have a reduced normal operation time specification (e.g., in exchange for cost saving or any other arrangement). In this configuration, the distribution system 100 can selectively disconnect and connect various loads 106 based on the associated cost specification. In a general sense, power distribution system 100 may be selectively and dynamically disconnected or connected to meet any combination of performance specifications.

[0037] In some embodiments, different SSPCs 102 may provide the same performance specifications to the attached loads 106. In this configuration, the power distribution system 100 may utilize the SSPCs 102 to balance power distribution or interruptions in power distribution between the various attached loads 106. For example, the power distribution system 100 may rotate temporary disconnections between the various SSPCs 102 to balance power distribution to the various attached loads 106.

[0038] In addition, the power distribution system 100 can receive input (e.g., as feedback) from any number of sources for power control. For example, the power distribution system 100 can allow manual control by a user, which can be local or remote. As an illustration, the power distribution system 100 can provide information associated with the load levels of various loads 106 attached to any SSPC 102. Such information can be in the form of data, performance category form (e.g., high, low, abnormal, etc.), or any other suitable form. The user can then selectively control the SSPC 102 to connect or disconnect the various loads 106. In addition, the power distribution system 100 can use the HMI 116 to provide an alarm (e.g., an audio alarm, a visual alarm, etc.) when a selected condition (e.g., a load condition of any one of the loads 106 (e.g., current or future power demand), a reduction in the performance or capacity of the input power source 104, etc.) is met (e.g., when the feedback data deviates beyond a selected threshold). As another example, the power distribution system 100 can receive switching criteria associated with when and / or how to achieve disconnection or connection of the load 106. For example, the switching criteria may include, but are not limited to, start and stop conditions or thresholds for any of the loads 106 (e.g., connection and disconnection conditions), delays after a condition or threshold is met, etc. In addition, such switching criteria may be preloaded on the power distribution system 100 and / or configurable by a user (e.g., via the HMI 116). As another example, the power distribution system 100 may more generally provide automated control based on any combination of input conditions or feedback (e.g., start and stop conditions, delay levels after a particular threshold has been reached, etc.).

[0039] It is also contemplated herein that the power distribution system 100 can be implemented in a variety of ways within the spirit and scope of the present disclosure. For example, the power distribution system 100 can be coupled to or integrated with a power distribution unit (PDU) for providing power to a plurality of loads 106. In some embodiments, the SSPC 102 is provided as a standalone component on the upstream side (e.g., "line side") of the PDU to control loads 106 connected downstream of the PDU. In some embodiments, the SSPC 102 is integrated into the PDU (e.g., integrated into the line side of the PDU). In some embodiments, the SSPC 102 is provided within a switchgear array.

[0040] Now refer to Figure 3 , Figure 3 is a flow chart illustrating steps performed in a method 300 for dynamic power delivery according to one or more embodiments of the present disclosure. Applicants note that the embodiments and enabling techniques previously described herein in the context of the power distribution system 100 should be interpreted as extending to the method 300. However, it should also be noted that the method 300 is not limited to the architecture of the power distribution system 100.

[0041] In some embodiments, the method 300 includes a step 302 of receiving performance specifications of two or more loads 106. The performance specifications may generally include performance requirements for each of the loads 106, such as, but not limited to, uptime or reliability requirements. Furthermore, the performance parameters of the various loads 106 may be the same, may be different, or may vary over time.

[0042] In some embodiments, the method 300 includes a step 304 of receiving feedback data from any one of the two or more loads 106 or at least one of the input power sources 104. In some embodiments, the method 300 includes a step 306 of directing two or more SSPCs 102 to disconnect or connect any of the two or more loads 106 from or to the input power source 104 to achieve performance specifications of the two or more loads 106 based on the feedback data, wherein each of the two or more SSPCs 102 is coupled to a different one of the two or more loads 106 (e.g., to maintain an inrush current below a selected threshold when disconnecting or connecting any of the two or more loads to the power source).

[0043] For example, feedback data associated with input power source 104 may include past power conditions, current power conditions, or expected power conditions provided or expected by input power source 104. In this manner, such feedback data may be used to dynamically balance power to loads 106 (e.g., selectively connect or disconnect any of loads 106) based on feedback data associated with available power from input power source 104 to meet performance specifications of loads 106. As another example, feedback data associated with loads 106 may include past load conditions, current load conditions, or expected load conditions of any of loads 106. In this manner, such feedback data may be used to dynamically balance power to loads 106 (e.g., selectively connect or disconnect any of loads 106) based on feedback data associated with changed load conditions of any of loads 106 to meet performance specifications of all of loads 106.

[0044] The subject matter described herein sometimes shows different parts that are contained in other parts or connected with other parts.It should be understood that this architecture depicted is only exemplary, and in fact many other architectures can be realized, and these other architectures realize the same function.In a conceptual sense, any arrangement of the parts realizing the same function is effectively "associated" so that the desired function is realized.Therefore, any two parts combined to realize a specific function herein can be regarded as "associated" with each other so that the desired function is realized, regardless of the architecture or intermediate parts.Similarly, any two parts so associated can also be regarded as "connected" or "coupled" to realize the desired function, and any two parts that can be so associated can also be regarded as "coupleable" to realize the desired function.Specific examples that can be coupled include but are not limited to physically interactive and / or physically interactive parts and / or wirelessly interactive and / or wirelessly interactive parts and / or logically interactive and / or logically interactive parts.
