Technique Reducing Power Loss in Three-Level DC-DC Converter Devices with Zero-Voltage and Zero-Current Switching Method

This research paper presents zero-voltage and zero-current switching method for full-wave three-level DC-DC converters, to reduce power loss due to switching of devices in the DC-DC converter.Principles and methods of reducing power loss for this research will be used to switch devices when turn-on and turn-off by controlling the generation of PWM signals with phase shifting with microcontroller DSPTMS320F28377S.The results, when simulated by MATLAB/Simulink program, compare with the prototype, found that when combined with the non-linear load in the ZVZCS state, the efficiency is equal to 89.90%.Accordingly, connected to the non-linear load in the no-ZVZCS state, the efficiency is equal to 81.20%.
