Abstract:
 The operating principle of diode-clamped single phase 9-level inverter was analyzed firstly,and its useful switching vectors of the inverter were obtained. A novel space vector pulse width modulation ( SVPWM) was presented based on pulse-shifting,according to volt-second balance principle and two-vector modulation rule. By analyzing the pulse-shifting condition within one normal switching period,the criterion for judging pulse type was also proposed. Based on different pulse type,the computing method of the start and end voltage vector were different,and their dwell time were also different. The SVPWM control system was implemented using a field programmable gate array ( FPGA) circuit as the hardware simulation platform,whose clock and resource utilization are evaluated. The simulation and experimental results demonstrate that the presented control strategy has good control effect,and balances the capacitor voltages better.
