PWM control method for single-phase to three-phase converter with a three-phase switching power module

In this paper, a simple single-phase to three-phase converter composed of a three-phase switching power module is presented and its PWM control method is investigated. The construction of the double converter is very simple. A PWM control technique based on instantaneous voltage vector of the three-phase inverter with four switching devices is investigated in detail. The PWM control system of the double converter is shown. The feasibility of the converter system is verified by some simulation and experimental results.
