| Abstract: | A novel asymmetric 5-level inverter and a new modulation method for the inverter are analyzed in this paper. A Compound control method is proposed to reduce voltage distortion in the condition of the nonlinear load, which is based on feedforward load current and output voltage and does not require accurate parameters. The compound control method is easy to design. The feasibility of the method is verified by simulation and experiment. |
