Abstract
A quasi-resonant PWM inverter performs stable resonant operation utilizing a simple control system and a highly efficient inverter operation. A first condenser is connected between a connecting point between first and second main switches and to the first side of the first main switch. A second condenser is connected between the connecting point and the second side of the second main switch. The respective first and second sides of the first main switch and second main switch are connected to a DC power source having a first dividing point for the first potential and a second dividing point for the second potential. A terminal of a first auxiliary switch is connected to the first dividing point; and a terminal of a second auxiliary switch is connected to the second dividing point. A reactor is connected between the connecting points of the first and second auxiliary switches and the first and second main switches.
