摘要：

In this paper, a novel three-phase AC/AC converter is proposed. The proposed converter consists of six power switches, three capacitors, three input inductors and three output inductors. The proposed converter has several advantages such as sinusoidal input-output current, adjustable frequency, unity input power factor and lower switch cost etc. Based on the sinusoidal pulse width modulation techniques and zero vector control strategy, the converter combines three-phase AC/DC converter and three-phase DC/AC inverter to generate a single-stage converter controlled in the same period. By fixed capacitor ratio, the duty functions of converter and inverter are operated in optimum period for more stable control. The software VisSim and TI TMS320F2812 are adopted to implement the proposed converter. Besides, the mathematic model of the proposed converter is established by the state average technique. Finally, some experimental results are compared with the proposed theory for verification.
