| 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SABER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.

| Abstract: | 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 compen... |
