An improved neutral-point-potential balance control strategy for three-level PWM rectifier

Neutral point potential balance control is very important to three-level neutral-point-clamped (NPC) rectifiers. In this paper, the balance control strategy is studied with three-level space vector pulse width modulation (SVPWM) algorithm based on reference voltage decomposition. An improved neutral-point potential balance control strategy based on balance factor is proposed and the principle is analyzed. Simulation and experimental results verify the validity of the control strategy.
