Isolated Boost DC-DC Converter with Three Switches - 2017

ABSTRACT:

This paper documents a replacement three-switch, isolated boost dc-dc converter. The major features of the proposed converter are as follows: 1) continuous input current; two) reduced one active switch, one extra diode, and one additional capacitor; 3) unchanged primary and secondary voltage waveforms of the transformer when the duty cycle is changed; and four) removal of the snubber circuit. This paper presents the operating principles, analysis, parameter style pointers, and simulation results for the proposed converter. To verify the performance of the proposed converter, a 400 W prototype was constructed with a forty-60 V dc input. A PID controller was used to take care of the dc output voltage at four hundred V. The simulation and experimental results matched those of the theoretical analysis.
