This work demonstrates the design and implementation of a digitally encoded Sinusoidal Pulse Width Modulation strategy for the switching of bi-directional secondary side power switches of an AC-link. Through this method, high frequency (200 kHz) half sinusoid or haversine voltage pulses produced by the Parallel Loaded Resonant converter working in discontinuous mode at primary side are converted to low frequency (400/60/50 Hz) waveforms at the output. This control strategy allows the converter to operate at high power density, as soft switching (ZCS/ZVS) is possible at both the turn-on and turn-off of switches. Also through this strategy the output waveform at load will have low Total Harmonic Distortion (THD).
