摘　　要：提出了一种新的具有高输入-输出电压转换率的升压变流器,该变流器含有两个升压电感和两个开关管,并采用一个耦合两个升压电感电流通道的辅助变压器,通过恒频控制可在较宽的负载范围和输入电压范围内实现对维持输出电压的调节。由一个1kW的实验原型电路证实了该变流器的性能。This paper introduced a new boost converter with a high input-output voltage conversion ratio. The converter included two boost inductors and two switches. The output voltage regulation of the proposed converter is achieved in a wide load and input voltage range with constant-frequency controlled by employing an auxiliary transformer that couples the current paths of the two boost inductors. The performance of the proposed boost converter is verified on a I kW prototype circuit.
