 Abstract

This paper develops and analyses a boost-type push–pull converter with a reduced number of switches. The newly designed converter mainly consists of five diodes, two switches, two inductors, a transformer and two capacitors. By tuning the duty cycle and the transformer ratio, different voltage gains of the proposed converter can be obtained. It is notable for its electrical isolation characteristics. When compared with traditional step-up converters, the step-up module and converter module share the same switch. In addition, the control of the converter becomes easier to implement, and it has better stability and a reduced volume. It should be mentioned that the number of switches in the proposed converter is decreased but maintains the same voltage stress when compared to the traditional structure. The operating principle of proposed converter is demonstrated, which is followed by the design of the component parameters. To validate the feasibility of the proposed topology, an experimental prototype is constructed to verify its correctness and practicability of the proposed converter when compared with the conventional converter.
