Xiaohui Xu,Kui Wang,Nianzhou Liu,Zedong Zheng,Yongdong Li 전력전자학회 2019 ICPE(ISPE)논문집 Vol.2019 No.5
In order to increase the output power and voltage levels, a nine-level ANPC/H-Bridge inverter for high power medium voltage motor drive applications is presented in this paper. Each phase of this inverter consists of two fivelevel ANPC bridges and all the phases are powered by a common DC-link, which is very suitable for ship integrated electric propulsion with open-winding multi-phase motors. A hybrid modulation method is adopted to control this inverter. The series connected or high-voltage switches in all the fivelevel ANPC bridges are operated at fundamental frequency and the other switches are controlled with PS-PWM, which is easy to implement and can achieve the natural voltage balance of the neutral-point potential and flying capacitor voltages. A capacitor voltage balancing method based on this hybrid modulation method is also proposed. Simulation and experimental results are presented to verify the validity of this method.
