ZERO VOLTAGE SWITCHING IN THE PWM HALF BRIDGE TOPOLOGY WITH COMPLEMENTARY CONTROL AND SYNCHRONOUS RECTIFICATION

A ha&=bridge DClDC converter with cnmplementury control und seydriven synchronous rectifcution is described in this paper. Zero Voltage Switching is unutyzed taking into account the eflect of the parasitic capuci&unces the synchronous rectijers cf the secondury side. The main udvuntuges of this converter, that are high eficiency for bw output voltuge, sop-switching for priinary urui secondary switches ami very smuN output jfilrrr, are shown in an acfuul prototype.
