摘　　要：基于软开关PWM技术与均流技术的结合能很好地满足大功率电源的性能,将最大电流法作为均流方法选择,采用均流控制芯片UC3907设计了电源的控制电路,可以实现多电源模块并联组成更大功率的电源系统.最后给出两台电源并联运行的效果.In view of the fact that the performance index of high power supply can be attained by combining the techniques of PWM based on soft switch and current equalizing, the control circuit of the power supply was designed by using the current equalizing chip UC3907 in terms of selecting the maximum current as current equalizing,which can make multi-power supply modules construct a higher power supply system. Finally, the experimental result of parallel operation of two power supplies was presented.
