Abstract

High energy conversion efficiency of grid tied inverters for renewable energy applications constitutes a prime design goal of these systems. On the other, presently employed PWM techniques seem to set a bound to the efficiency since the associated switching losses are difficult to reduce. This paper introduces a new approach to synthesis of sinusoidal waveform in which the switching frequency is relatively low (in contrast to PWM technique) which yield a major reduction in switching losses. Even though the switching frequency is low, the harmonic content at the inverter's output is extremely low which allow for significant size decrease of the output filter. The method is based on a multiplication like principle, which is described in this paper.
