摘要

针对中性点箝位型三电平光伏并网逆变器，提出了一种中性点电压平衡控制算法。推导了中性点电流的数学模型。分析了间断脉宽调制(DPWM)方法对中性点电压的影响。通过比较反馈中性点电压与滞后宽度的误差，选择DPWM控制中性点电压的方法。仿真和实验结果验证了所提中性点电压平衡控制算法的正确性和有效性。

Neutral point voltage-balanced control method based on discontinuous pulse width modulation for a NPC 3-level inverter

A neutral point voltage-balancing control algorithm is proposed for a neutral-point-clamped (NPC) three-level photovoltaic (PV) grid-connected inverter. The mathematical model of the neutral point current was deduced. The influence on the neutral point voltage for discontinuous pulse width modulation(DPWM) methods was analyzed. Comparison of the error between feedback neutral point voltages and the hysteresis width was used to choose a DPWM method to control the neutral point voltage. Simulation and experimental results verify the correctness and validity of the proposed neutral point voltage-balancing control algorithm.
