Abstract :
The paper proposes a single-phase to three-phase AC/AC converter with regeneration and adjustable power factor. The circuit architecture is a capacitor connected in series with a single-phase full-bridge and three-phase full bridge. The proposed converter has several advantages such as adjustable power factor, sinusoidal input current, adjustable frequency, single stage control, energy regeneration, and reducing the switching loss etc. Based on a generalized zero vector technique and dead-band control, the converter combines a single-phase converter and three-phase inverter to form a single-stage converter of single-phase AC to three-phase AC. Both VisSim simulation program and DSP TMX320F28335 are employed to achieve digital control for power factor correction and feedback control. Finally, some experimental results are compared with the proposed theory for verification.
