Abstract
A three-phase converter configured to be coupled between a direct current system and an alternating current system to perform interconversion between a direct current and an alternating current, where the three-phase converter includes a switching network, a three-phase filter coupled to the switching network, a sampling circuit coupled to the three-phase filter, a control circuit coupled to the three-phase sampling circuit, an active damping circuit coupled to the control circuit and the sampling circuit, and a modulation circuit coupled between the active damping circuit and the switching network, where the sampling circuit is configured to obtain three-phase currents in the three-phase filter, and send the three-phase currents to the active damping circuit, the active damping circuit is configured to obtain new three-phase modulated waves according to the three-phase currents, and transmit the new three-phase modulated waves to the modulation circuit.
