| Abstract |
Zero Voltage Transition Pulse Width Modulation (ZVT-PWM) converter with active snubber circuit was proposed on this paper. The converter that has been proposed snubber circuit can be operated at the condition of light load range, and this converter is turned on and off near by Zero Voltage Switching (ZVS) or Zero Current Switching (ZCS). If the stress of voltage and current are not occurred at the main switch and main diode, we subjected the allowed level of voltage and current on the auxiliary switch and auxiliary diodes. By proposed 750[W], 80[kHz] PWM boost converter to apply soft switching on the power of total output, the loss of main switch to compare with hard switching was reduced about 27[%], and the loss of total circuit was reduced about 36[%]. The total efficiency was increased about 6[%] to compare with general converter. |
