Abstract

This paper presents a space vector pulse width modulation and proportional resonant control scheme for single-phase three-level rectifier for electric railway traction applications. The proposed SVPWM modulation has been tailored to the single-phase rectifier without an additional PLL. Moreover, vectors and vectors sequence have been carefully designed to achieve neutral point voltage balance. Based on the analysis of transfer function of rectifier system, the defect of classical PI control scheme has been discussed. And then, PR control is deployed in the current inner-loop to eliminate steady-state error and enhance the control effects. A series of simulations and experimental tests demonstrate the effectiveness of SVPWM+PR control.

Abstract

The topology of neutral-point clamped (NPC) is widely used for multilevel inverters, and the balance of the neutral-point voltage is one of the key technologies which determines the performance of Permanent Magnet Synchronous Motor(PMSM). Repetitive control can ensure control precisions by keeping the appropriateness of the control signal when the system is stable. In this paper, neutral-point balancing control scheme and repetitive control scheme used in the algorithm of PMSM drive system based on three-level topology was established to improved the dynamic and static performance of system. Our results indicates that the repetitive+PI control scheme provides better transient and steady state performance than classical PI control scheme for PMSM.
