[0001] The invention relates to a radar power supply and power amplifier integrated system, belonging to the technical field of radar structure. Background Art

[0002] Radar equipment is a kind of equipment with high power demand. The design of reasonable power supply architecture is the key to the reliable operation of radar equipment. There are various forms of power supply architecture, and there are two main ways to divide it by function: decentralized rectification and voltage stabilization; centralized rectification and decentralized voltage stabilization. Both have their advantages and disadvantages, which are mainly reflected in single failure rate, array weight, dynamic response parameters, etc. The power amplifier component realizes the conversion of electrical power to radio frequency energy and is the core module of radar radiation function.

[0003] However, in many current applications, the power supply architecture and power amplifier components are relatively "separated" in terms of function, and there is no effective and reasonable unified design consideration, resulting in poor interconnection design and poor dynamic response between the two functional modules. In terms of health management, there is no good overall planning between the two, which easily leads to management redundancy or deficiency. And as equipment has higher and higher requirements for reliability, maintainability, and "three transformations (institutionalization, standardization, and proceduralization)", the energy flow composed of electrical energy and radio frequency energy has a lot of room for improvement.

The rectifier cabinet connects the power supply and the slip ring, converts the three-phase AC voltage provided by the power supply into DC high voltage and transmits it to the slip ring. The slip ring is connected to the power supply control backplane. After the slip ring divides the DC high voltage into multiple paths, the DC high voltage flows through the power supply control backplane and the power supply control adapter board in sequence to reach the power supply module. A plurality of signal transmission paths are provided in the power supply control backplane, and the output end of the signal transmission path is connected to the power supply control adapter board.

[0020] Example 2.

[0021] like Figure 1 As shown, the present invention provides a radar power supply and power amplifier integrated system, including: a power supply, a rectifier cabinet, a merge ring, 4 power supply control backplanes and 36 cold plate assemblies, and the cold plate assembly is composed of a power supply control adapter board, a unit component and a cold plate.

[0022] In this embodiment, the power source is the platform power distribution cabinet; Figure 1 As shown, the rectifier cabinet consists of rectifier components 1, rectifier components 2, rectifier components 3 and rectifier components 4. The four rectifier components together convert the three-phase AC voltage (380V / 50Hz) provided by the platform distribution cabinet into DC high voltage (500VDC). Figure 1 The red arrow in the middle indicates the direction of current transmission, which is transmitted to each amplifier component in the array in the form of a busbar. The array refers to the combination of the power supply control backplane and the cold plate. The rectifier cabinet only completes the AC / DC conversion, and the high voltage is transmitted to the array. Under the same power, high voltage transmission can effectively reduce the weight of the array, transmission loss and transmission line diameter. Provide a variety of power supply methods for high-power equipment.

[0023] like Figure 1 As shown, the bus ring transmits the high-voltage bus power generated by the rectifier cabinet from the rectifier cabinet to each power amplifier component of the array, which is a key link in energy transmission. In this embodiment, the array power is relatively large, and the array is divided into four relatively independent sub-arrays. Correspondingly, the inside of the bus ring is designed into four independent rings, each of which has an independent high-power transmission capacity (in this embodiment, it has a power supply capacity of 30KW), which can meet the power demand of the entire array power supply. In this embodiment, it can meet the 120KW power demand of the array.

Figure 1 Red arrow in the figure), wave control ( Figure 1 orange arrows in the Figure 1 The green arrow in Figure 1 Signals such as CAN in the power supply control backplane are distributed to each unit component through the power supply control backplane. The mixed multi-signal is uniformly collected and processed by the power supply control backplane, which can greatly optimize the array routing, but it places high demands on the power supply control backplane for large and small currents, high and low frequency signal processing. Considering the large scale and high installation precision of the system, the whole array is divided into four sub-arrays, and each sub-array is matched with a power supply control backplane.

The main function of the power supply control adapter board is to connect the power supply control backplane and the unit components. The unit components include an integrated power supply module, a control communication module and a power amplifier component. The power supply, wave control and communication control are summarized and distributed to each power supply module and power amplifier component. The panel of the power supply control adapter board only has an RF input interface and a debugging standby interface. Among them, the debugging standby interface is used for program download or whole machine joint debugging. When the debugging standby interface is not used, it is covered with a cover plate, which is both beautiful and prevents human damage. The power supply module reduces the bus high voltage to a suitable level to power the power amplifier component, and generates other auxiliary levels to power the control, communication and other circuits. Considering the versatility and modular design of the solution, each component has a power of 500W, which can meet most power demand occasions and is compatible with continuous wave and pulse multiple load modes. The power amplifier component is the core link of power conversion. It adopts laser sealing and welding technology, standardizes the production process, and improves the modularization level. The cold plate adopts liquid cooling. The power amplifier component is assembled close to the cold plate through thermal conductive glue, making full use of the cold plate heat dissipation and optimizing the array weight.

[0027] The power supply module steps down the 500V DC high voltage to 28V to power the power amplifier components, and also generates +12V and +5V to power the control communication module.

Each set of rectifier modules has an output voltage of 500V and an output power of 30KW, which is sent to each sub-array through the merge ring to provide the main energy for the array operation. In addition, the rectifier cabinet includes output leakage current detection and alarm functions to improve power supply safety.
