In this paper the salient features of four different topologies of low frequency sinewave inverter with high frequency link and PWM control is presented. The inverters employ ferrite cored transformers, inductors, resonant filters tuned to switching frequency( \geq 20 kHz) and power MOSFETS resulting in compact design. Equivalent circuit approach is used for analyzing all the four topologies and computer simulation The method of synthesizing the sinusoidal PWM waveform, as well as estimation of total harmonic distortion and response of the low pass filters using discrete time domain are presented along with relevant graph and waveforms.
