A novel three-phase power-factor-correction (PFC) rectifier with zero-voltage-switching (ZVS) in six main switches and zero-current-switching (ZCS) in the auxiliary switch is proposed, analyzed, and experimentally verified. The main feature of the proposed auxiliary circuit is used to reduce the switching loss when the six main switches are turned on and the one auxiliary switch is turned off. In this paper, a detailed operating analysis of the proposed circuit is given. Modeling and analysis are verified by experimental results based on a three-phase 7 kW rectifier. The soft-switched PFC rectifier shows an improvement in efficiency of 2.25% compared to its hard-switched counterpart at 220 V under full load.

In this paper, a new application of three-phase inverter using zero-vector control is proposed. In order to control the amplitude of output current, the d-q axis coordinate transformation, hysteresis controller and space vector strategy are adopted. Besides, the frequency of output current also can be adjusted by zero-vector control. Therefore, the proposed inverter has lower switching loss, higher system efficiency and better dynamic response. Use VisSim simulation software and TI TMS320F28335 chip to implement the proposed control strategy. The controller has several advantages such as easier to control, smaller circuit size and fully digital design etc. Finally, the experimental results are compared with the proposed theory for verifications.
