摘要

本文提出了两种新型的简化级联多相DC-DC升压功率变换器，具有高电压增益和低纹波特性。所有的简化都将有源开关器件的数量从2N减少到N，其中N为相数。第一个简化将感应器的数量从2N减少到N+1，并将二极管的数量从2N增加到(2N+1)。第二种简化将电感的数量从2N减少到N+1，并将二极管的数量从2N增加到(3N+1)。第二种简化需要比第一种简化具有更小额定电流的电感。通过考虑电感和开关功率器件之间的电压降，导出了输出电压作为负载电流函数的表达式。仿真和实验结果显示了所提出的级联多相DC-DC升压功率变换器的基本性能。

Simplified cascade multiphase DC-DC boost power converters for high voltage-gain and low-ripple applications

This paper proposes two new simplified cascade multiphase DC-DC boost power converters with high voltage-gain and low ripple. All simplifications reduce the number of active switching devices from 2N into N, where N is the phase number. The first simplification reduces the number of inductors from 2N into N+1 and increases the number of diodes from 2N into (2N+1). The second simplification reduces the number of inductors from 2N into N+1 and increases the number of diodes from 2N into (3N+1). The second simplification needs inductors with smaller current rating than the first simplification. The expressions of output voltage as a function of load current are derived by taking into account the voltage drops across the inductors and switching power devices. Simulated and experimental results are included to show the basic performance of the proposed cascade multiphase DC-DC boost power converters.
