| 摘 要： | 文章详细分析了单相SPWM逆变器中死区时间和开关器件固有特性对输出波形的影响，提出了1种基于重复控制的死区补偿策略，该方法有效地改善了输出电压的波形畸变。在l台400Hz、7．5kVA样机上的实验结果验证了该补偿策略的有效性。

| Abstract: | The influence of dead-time and inherence characteristics of switching devices on output voltage in single-phase SPWM inverters is analyzed in detail. A dead-time compensation strategy based on repetitive control is proposed. It can provide excellent inverter output voltage distortion correction. Experimental results on a 400 Hz 7.5 kVA prototype are presented to demonstrate the validity of the compensation strategy. |
