Description

Technical Field

[0001] The utility model relates to the technical field of computers, and in particular to a TLVR inductor circuit supporting power supply for a CPU and a GPU. Background Art

[0002] With the booming development of computing-intensive applications such as deep learning, artificial intelligence, and big data analysis, these technologies involve large amounts of data processing and complex model training. They require powerful computing power to process massive amounts of data, optimize complex neural network structures, and achieve fast model iteration and real-time applications. In addition, the real-time and accuracy requirements of these technologies have also prompted the demand for high-performance hardware to ensure fast and accurate computing and data processing. These applications require not only powerful computing power, but also efficient power management systems to support them. However, with the increasing complexity of computing tasks, the power consumption of CPUs and GPUs is also increasing year by year, and traditional inductor designs are beginning to appear unable to meet transient response requirements. In the power supply of CPUs and GPUs, traditional inductor designs, due to their inherent physical properties, often fail to adjust current output in time when facing rapidly changing loads, resulting in insufficient transient response speed. This not only affects the overall performance of the system, but may also cause voltage fluctuations, which in turn affects the accuracy of calculations. In order to make up for this shortcoming, engineers have to add a large number of large capacitors to the power supply line to smooth current fluctuations and ensure voltage stability through the fast charging and discharging characteristics of capacitors. However, although this method solves the problem to a certain extent, the addition of large capacitors means a significant increase in material costs, and its cost increases with the increase in capacity, which undoubtedly increases the overall hardware cost. Secondly, the introduction of large capacitors also occupies valuable PCB layout space, which is particularly critical in space-constrained high-performance computing systems. The increase in PCB space not only affects the system's integration, but may also cause heat dissipation problems, which in turn affects the stability and reliability of the system. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a TLVR inductor circuit supporting CPU and GPU power supply, aiming to improve the performance of CPU and GPU power supply, reduce costs and improve the overall efficiency and stability of the system.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

The PWM controller is connected to the power converter, and the TLVR inductor and the main inductor are connected to the power converter. The TLVR inductor includes a first coil and a second coil, and the first coil and the second coil are magnetically coupled.

[0006] In some embodiments, there are three sets of the power converter, the main inductor Lm, and the TLVR inductor. The PWM control terminal of the power converter is connected to the output terminal of the PWM controller, and the power input terminal of the power converter is connected to an input voltage.

[0017] In the figure: 100, PWM controller; 200, power converter; 300, TLVR inductor. Detailed Embodiment

[0018] The general idea of the technical solution provided by the present utility model is as follows:

[0019] Please refer to Figure 1 A TLVR inductor 300 circuit for supporting the power supply of the CPU and GPU, including a PWM controller 100, a power converter 200, a main inductor Lm, and a TLVR inductor 300. The PWM controller 100 is the PWM Cont in the figure, and the power converter 200 is the Powerstage Phase in the figure. The PWM controller 100 is connected to the power converter 200, and the TLVR inductor 300 and the main inductor are connected to the power converter 200. The main inductor Lm is the blue coil in the figure. The TLVR inductor 300 includes a first coil and a second coil, and the first coil and the second coil are magnetically coupled. Taking the first TLVR inductor 300T1 in the figure as an example, the first coil is the red coil in the first TLVR inductor 300T1, and the second coil is the black coil in the first TLVR inductor 300T1.

[0020] In a traditional inductor power supply system, when facing a rapid change in the load from light load to heavy load, the output current will increase rapidly. Since the inductors of each phase work independently, they must successively go through the steps of output voltage drop, passing through a comparator, PWM duty cycle increase, and output current increase, resulting in a long response time. When the current increases sharply, due to the power increase speed not keeping up, the output voltage may drop instantaneously, resulting in a large voltage fluctuation in the power supply output, which usually requires additional capacitors to absorb and stabilize the voltage.

[0021] In contrast, the TLVR inductor 300 technology significantly improves the performance of the power supply system. The traditional single - coil inductor is replaced by a dual - coil coupled inductor, whose structure is similar to a transformer, and a compensating inductor Lc is introduced in the coupling path. This design not only maintains compatibility with traditional multi - phase power supply solutions, but also significantly improves the response speed and stability of the power supply by adding the compensating inductor Lc.

[0022] During transient load changes, although the PWM signal adjustment method of the TLVR inductor 300 is similar to that of traditional multi - phase power supplies, both adjusting the output by changing the PWM duty cycle, the key difference is that when the PWM duty cycle changes, the current in the compensating inductor Lc will change accordingly. This change will quickly affect the inductors of other phases, enabling the entire power supply system to respond to transient current changes almost synchronously. Therefore, the total output current can be quickly adjusted to meet the load demand, effectively improving the transient response performance of the multi - phase power supply and reducing the need for large capacitors at the output.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] See Figure 1 , there are three sets of the power converter 200, the main inductor Lm, and the TLVR inductor 300. The PWM control terminal of the power converter 200 is connected to the output terminal of the PWM controller 100, and the power input terminal of the power converter 200 is connected to the input voltage. The circuit is a three - phase power supply system, providing a more balanced and stable power output, especially suitable for applications that require high power and high stability, such as servers, data centers, high - performance computing devices, etc. Connecting the PWM control terminal of the power converter 200 to the output terminal of the PWM controller 100 enables precise control of the power converter 200. The PWM controller 100 sends pulse - width modulation signals through the output terminal, and these signals control the on - off states of the switching elements in the power converter 200, thereby adjusting the magnitude and frequency of the output voltage. This control method enables the power converter 200 to dynamically adjust the output according to the load demand, improving the power efficiency and response speed.

[0025] See Figure 1 , the three first coils are connected in series in sequence.

[0026] See Figure 1, one end of the second coil and the main inductor Lm is connected to the output terminal of the power converter 200, the other end of the second coil and the main inductor Lm is connected to the output voltage and the feedback voltage, and the PWM controller 100 is connected to the feedback voltage and the auxiliary voltage, that is, VFB and Vaux in the figure.

[0027] See Figure 1 , further comprising a compensation inductor Lc. One end of the first coil of the first TLVR inductor 300 is connected to one end of the first coil of the second TLVR inductor 300. The other end of the first coil of the first TLVR inductor 300 is connected to one end of the compensation inductor Lc. The other end of the compensation inductor Lc is connected to one end of the first coil of the third TLVR inductor 300. The other end of the first coil of the third TLVR inductor 300 is connected to the other end of the first coil of the second TLVR inductor 300. This enhances the response ability of the circuit to load changes. When the load suddenly changes, the compensation inductor Lc can quickly adjust the current to meet the load demand, thereby improving the transient response speed of the power supply. When the load suddenly changes, the compensation inductor Lc can quickly adjust the current to meet the load demand, thereby improving the transient response speed of the power supply.

[0028] See Figure 1 , further comprising an input capacitor, that is, Cin in the figure. The positive and negative electrodes of the input capacitor are respectively connected to the input voltage and the ground wire. The input capacitor is used to filter out high-frequency noise and ripple in the input power supply and provide a relatively smooth input voltage for the power converter 200. This helps to improve the stability of the input end of the power supply and reduce the interference to the power input. When the load changes, the input capacitor can temporarily store energy to meet the instantaneous power demand, thereby reducing the fluctuation of the input voltage.

[0029] See Figure 1 , further comprising an output capacitor, that is, Cout in the figure. The positive and negative electrodes of the output capacitor are respectively connected to the output voltage and the ground wire. The output capacitor is used to stabilize the output voltage of the power converter 200 and filter out high-frequency noise and ripple at the output end. This ensures that the load can obtain a stable power supply, which is particularly important for sensitive electronic devices.

[0030] See Figure 1 , the ground terminals of the PWM controller 100 and the power converter 200 are connected to the ground wire.
