The Development of High Power 3 Level Inverter based on FPGA

Three-level neutral point clamping (NPC) converter has been widely applied in high power drive system. And in this paper, a novel method is proposed to realize this algorithm based on FPGA, And the system is consist of two parts, the DSP part and FPGA part, the DSP part includes the control algorithms and the FPGA part works to generate and putout 12 PWM pulses. And the system is tested and verified using both simulation and experimentation.
