Abstract	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 power 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
