摘　　要：为了解决航空三相静止变流器输出波形失真问题,详细分析了死区效应造成电压畸变的原因和由此带来的谐波成分。采用正弦脉宽调制(SPWM)控制技术,使变流器输出的波形更接近于正弦波,提出了设置死区与电压补偿相结合的控制方法,并通过SA-BER进行了仿真分析。同时,利用TMS320F2812数字芯片实现了相应的补偿策略。仿真和试验结果证明了该控制方法的有效性。In order to solve the problem of the distortion of the output waveform of aviation three-phase static current transformer（CT）,the reasons of voltage distortion and the harmonic component caused by dead-zone effect are analyzed in detail.The SPWM control technology is adopted to make the output waveform approaching sine wave,and the control method of combing the setting dead-time and voltage compensation is proposed.The analysis is simulated by SABER,and by using digital chip TMS320F2812,corresponding compensatory strategy is realized.The results of simulation and experiment prove the effectiveness of this control method.
