摘要：
Based on analyzing the working principle of the capacitor-clamped hybrid five-level inverter and the voltage balance control of capacitor, a single-carrier and dual-modulation waves PWM(Pulse Width Modulation) strategy applied to the capacitor-clamped hybrid five-level inverter is introduced. By controlling the charging capacity equal to the discharging capacity in one carrier period, the voltage balance of capacitor is kept, and the control of the hybrid five-level inverter is achieved with only one ePWM module of DSP(Digital Signal Processor), which reduces the control difficulty and minimizes the DSP consumption. Experimental results verify the correctness and feasibility of the proposed strategy. © 2018, Electric Power Automation Equipment Press. All right reserved.
