Research on SVPWM arithmetic of Neural-Point-Clamped three level PWM rectifier

SVPWM arithmetic of Neural-Point-Clamped three level PWM rectifier and it´s neutral-point potential balance control strategy is discussed in this paper. Then this paper gives the topology configuration and mathematic model. Do some research on three level PWM rectifier SVPWM arithmetic based on reference voltage decomposition and neutral-point potential balance control strategy based on adjust two-level plane tab instantly. Based on this modulate method, build up power net voltage directional vector control system of three-level PWM rectifier, use Matlab/Simulink to simulate and the simulation result prove the validity of the modulate method.
