在可编程模块化电源(本实施例中称为PSU)次级变压器设计4个1:1变比的输出线包如图2所示,每个输出线包输出经整流滤波后都为12V电压,每路整流滤波后的输出连接MOS管后进入电源输出端。PSU初始上电处于standby状态时,通过PMBUS总线与系统BMC通信,确认系统对PSU的供电输出要求。当系统要求PSU输出12V时,PSU内部DSP控制M1/2/3/4以及Q1/2/3导通,Q4/5/6关闭,使PSU内部4路12V输出并联,PSU对外输出12V满足系统供电要求。每路输出设置防倒灌电路(基于LM5050芯片组成的ORING电路),过流过压保护电路,当每一路输出出现故障时,LM5050芯片控制对应路输出隔离MOS管关闭,避免影响其他分路的正常运行。此时PSU对外12V供电电压正常,输出功率减小。PSU通过PMBUS通信产生报警,系统降频,减小功耗,从而避免因PSU输出功率减小而导致系统宕机,为后期维护赢得时间。当系统要求PSU输出54V时,DPS控制调整变压器PFM频率使4个分路输出13.5V电压,同时Q4/5/6导通, M1/2/3/4以及Q1/2/3关闭。PSU内部4路输出串联,满足54V电压输出,为GPU服务器系统供电。这样同一PSU,根据内部FW的控制,可以满足多种场景的服务器系统供电需求,极大提高了PSU的通用性。In the programmable modular power supply (referred to as PSU in this embodiment) secondary transformer design four 1:1 ratio output line package as shown in Figure 2, each output line package output is 12V voltage after rectification and filtering , each rectified and filtered output is connected to the MOS tube and then enters the output terminal of the power supply. When the PSU is initially powered on and in the standby state, it communicates with the system BMC through the PMBUS bus to confirm the system's power supply output requirements for the PSU. When the system requires the PSU to output 12V, the internal DSP of the PSU controls M1/2/3/4 and Q1/2/3 to turn on, and Q4/5/6 to turn off, so that the 4 internal 12V outputs of the PSU are connected in parallel, and the PSU outputs 12V externally to meet the requirements of the system. Power requirements. Each output is equipped with anti-backflow circuit (ORING circuit based on LM5050 chip), overcurrent and overvoltage protection circuit. When each output fails, the LM5050 chip controls the corresponding output isolation MOS tube to turn off to avoid affecting the normal operation of other branches. run. At this time, the external 12V power supply voltage of the PSU is normal, and the output power is reduced. The PSU generates an alarm through the PMBUS communication, the system frequency is reduced, and the power consumption is reduced, thereby avoiding system downtime caused by the reduction of the PSU output power and gaining time for later maintenance. When the system requires the PSU to output 54V, the DPS controls and adjusts the PFM frequency of the transformer to make the 4 shunts output 13.5V voltage, while Q4/5/6 is turned on, and M1/2/3/4 and Q1/2/3 are turned off. The 4 outputs inside the PSU are connected in series to meet the 54V voltage output and supply power for the GPU server system. In this way, the same PSU, according to the control of the internal FW, can meet the power supply requirements of the server system in various scenarios, which greatly improves the versatility of the PSU.

Each output terminal of the PSU is connected with parallel isolated output MOS transistors and series MOS transistors. The PSU controls the conduction and shutdown of the MOS transistors according to different power supply requirements in the system, so as to realize the parallel connection or series connection of four outputs, so as to meet different output power supply voltage requirements. Each power supply is designed with an overvoltage and undervoltage protection circuit. When 4 circuits are in parallel operation, the output of the isolated MOS tube will be turned off immediately if each circuit fails, without affecting the power supply of the system by other branches, so as to meet the power supply requirements of the system to the greatest extent. When the PSU is initially powered on and in the standby state, it obtains the power supply requirements of the server system through PMBUS communication, controls the internal MOS tube and voltage drive circuit, and matches the system power supply.
