【Abstract】 The paper proposes a novel subway traction power supply system(DC 1500V)based on three-level voltage source PWM rectifier. It has many merits, such as energy saving, high power factor, low harmonic current, easy modularization and easy redundancy design. The paper mainly introduces the circuit topology, parallel control scheme, and three-level rectifier control scheme. At the end, simulation and experimental results are presented.更多还原
