Abstract

A three-phase two-leg neutral point clamped converter with space vector pulsewidth modulation scheme (SVPWM) is presented for power factor correction. The adopted three-level converter has less power switches compared to the conventional three-level three-leg converter. Only eight power switches and four clamping diodes with voltage stress of half DC bus voltage are adopted in the circuit configuration. A space vector pulsewidth modulation scheme is adopted to reduce the switching state of power switches. Based on the adopted control scheme, a proper voltage vector is generated on the AC terminal for drawing the sinusoidal line currents with unity power factor. The simulation results are provided to verify the effectiveness of the proposed control strategy.
