DUAL POWER CONVERTER AND METHOD OF MODIFYING THIS DUAL POWER CONVERTER

Abstract

The invention proposes a dual-power converter and a method for controlling such a dual-power converter, the dual-power converter comprising a three-phase bridge branch and a controller. Each phase bridge branch comprises a first conversion module, a second conversion module, a third conversion module, a fourth conversion module, a fifth conversion module, and a sixth conversion module, and a controller that controls the first conversion module, the second conversion module, the third conversion module, the fourth conversion module, the fifth conversion module, and the sixth conversion module to switch on and off, so that each phase bridge branch enters a positive half-wave cycle state, a positive dead zone state, a positive zero state, a complete zero state, a negative zero state, a negative dead zone state, and a negative half-wave cycle state.
