A novel approach to achieve nearly sinusoidal line current rectification of three-phase utility voltages is presented. The scheme incorporates two step-up dc-dc converters to modulate the dc-link currents at the third-harmonic frequency. The modulated currents are then circulated through the ac-side of the diode-bridge rectifier, using a zigzag autotransformer. Simulation results for a three-phase, 208-V (line-to-line), 1-kW system are presented. Results from experimental investigations on a laboratory model are included, supporting the concept.
