| Abstract: | This paper introduces a PWM controller based on FPGA and Digital Signsal Processor (DSP) for hybrid 7-level inverter, which adoptes a direct PWM method. The principle, configuration and design of the controller are present-ed. Experimental results demonstrate that the controller is simple and easy to realize and debug, and it can output multi-level voltage with better harmonics spectrum. |
