摘　　要：效率和并网电流电能质量是并网逆变器的两个重要指标,PWM调制方式对效率和并网电流电能质量存在关键的影响。比较了连续空间矢量调制和不连续空间矢量调制两种方式对逆变器损耗和并网电流电能质量的影响。并在10kW三电平T型并网逆变平台上进行了实验验证。Efficiency and power quality are among the most important indices of grid-connected inverter. Pulse width modulation has direct impact on these two indices. The continuous and discontinuous PWM schemes were compared from the loss and power quality of the inverter. Results were validated by experiment on 10kW T-type three-level Inverter.
