| 摘 要： | 逆变控制技术直接影响三相应急电源（EPS）输出波形的质量和整机效率。文中采SVPWM算法和数字控制技术，与传统SPWM算法相比，提高了EPS输出波形的质量和输出电能的效率；波形控制中采用电压瞬时值内环、平均值外环的双环控制，降低了波形畸变率，使正弦波电压输出更稳定。

| Abstract: | The output quality and efficiency of the three-phase emergency power supply are directly influenced by the control technology of inverters.The SVPWM algorithm and digital control technology are adopted in this paper.Comparing the conventional SPWM algorithm,the new algorithm could improve the EPS＇s output waveform quality and power efficiency, The double loop control,which is based on instantaneous-value inner loop and average value outer loop,could decrease the waveform distortion,and output more stable sine wave voltage. |
