ABSTRACT:
A method of converting a DC voltage to a sinusoidal AC voltage by way of a circuit comprising a single-phase inverter in a bridge configuration is disclosed. To output a voltage to a truly sinusoidal pattern even in the presence of load variations, the method provides for control of the inverter switching using the sliding mode technique and pulse width modulation with a three-level output voltage. Also disclosed is a circuit for implementing the method.
