Abstract :
A sinusoidal PWM inverter with MOSFETs controlled by an extremely small magnetic core is presented, which is simple and of high efficiency under high frequency switching. The circuit is based on the principle of the transistor core multivibrator. However the saturable core is used for PWM in the gate drive circuit. This inverter is especially suitable for small UPS system.
