| Summary: | 碩士 === 華梵大學 === 電子工程學系碩士班 === 102 === The analysis design and experimental results of a Current-Fed Boost Converter with Soft Switching (BCSS) research. Where in the phase shifted full-bridge converter main configuration, which is based on the UC3875 PWM control signal based.This component is available for the phase shift of the clock signal after it timing to modulate the PWM duty cycle, allowing the converters to the upper arm with zero current switching (ZCS) and lower arm with zero voltage switching (ZVS),that may reduce the switching loss at turned on or off. Also, to get a better voltage regulation, this circuit using a voltage negative feedback to control converte.
While the converter to give better regulation, using the transformer’s parasitism element. Parasitism element is the primary side transformer leakage and secondary side winding capacitance. Both of them consist of resonant circuit. And that we use of this parameter, complete a boost up converte with input 35Vdc~45Vdc and output 240 Vdc /0.48A
