Modeling and Analysis of Zero Voltage Switching PWM Half Bridge DC/DC Converter

영전압 스위칭 PWM 하프 브릿지 컨버터의 모델링 및 분석

The circuit effects due to the transformer primary side series equivalent inductance in the Zero Voltage Switching Pulse Width Modulated Half Bridge DC/DC Converter and its impact on the effective duty are analyzed. The steady state equations and the small signal model of the converter are derived incorporating the effects of the complementary control and the utilization of transformer primary side series equivalent inductance. The open plant dynamics are analyzed on the basis of the model derived. The model predictions are confirmed by experimental measurements.
