This paper proposed a novel control scheme for rectifier in 3-level neutral-point-clamped (NPC) converter for propulsion of high speed maglev train. In rectifier, the voltage and current are regulated by closed-loop in d-q reference frame. The fluctuation of neutral-point voltage is analyzed, and a new SVPWM modulation strategy is presented to make the NP voltage balance. The performance of rectifier...
