PROJECT TITLE :
Isolated Boost DC-DC Converter with Three Switches - 2017
This paper documents a brand new three-switch, isolated boost dc-dc converter. The major features of the proposed converter are as follows: 1) continuous input current; 2) reduced one active switch, one additional diode, and one extra capacitor; 3) unchanged primary and secondary voltage waveforms of the transformer when the duty cycle is modified; and 4) removal of the snubber circuit. This paper presents the operating principles, analysis, parameter design tips, and simulation results for the proposed converter. To verify the performance of the proposed converter, a 400 W prototype was created with a 40-sixty V dc input. A PID controller was used to keep up the dc output voltage at 400 V. The simulation and experimental results matched those of the theoretical analysis.
