dc.description.abstractThe specific circuit effects in the phase-shifted, zero-voltage switched, pulse width modulated (PS-ZVS-PWM) converter and their impact on the converter dynamics are analyzed. The small-signal model is derived incorporating the effects of phase-shift control and the utilization of transformer leakage inductance and power FETs junction capacitances to achieve zero-voltage resonant switching. The thesis explains the differences in the dynamic characteristics of the PS-ZVS-PWM converter and its PWM counterpart. Model predictions are confirmed by experimental measurements.en
