Abstract :
This paper presents a new PWM control scheme for a single-phase three-level PWM rectifier to improve the power quality. A diode bridge with two power switches is adopted as a PFC circuit to achieve a high power factor and low harmonic distortion. The control scheme is based on a look-up table with hysteresis current controller (HCC). Based on the proposed control scheme, the line current is driven to follow the sinusoidal current command which is in phase with the supply voltage. The software simulation and experimental results are shown to verify the proposed control scheme. It is shown that the measured line current harmonics and power factor satisfy the IEC 1000-3-2 requirements
