Summary:This paper presents a new modulation method for high-frequency link bidirectional three-phase AC/DC converter based on matrix converter. Since the matrix converter does not have electrolytic capacitor, it achieves high power density and long lifetime system. The modulation method performs bidirectional active and reactive power control with sinusoidal line current by using optimal duty cycle and phase shift. The optimal duty cycle and phase shift are determined by numerical calculation based on the system mathematical model. Experimental results employing a 1kW laboratory prototype verify the capability to control active and reactive power with sinusoidal line current.
