摘　　要：针对三相整流控制电源存在三相交流电压波形畸变造成整流电压过零点检测不可靠的问题,对采用硬件比较电路产生脉冲的整流方案做了适当改进,采用了一种把交流信号经过FIR滤波之后,通过数字的方法产生整流同步信号的整流方案。通过软件MATLAB仿真表明,采用该方案可以产生稳定可靠的整流同步信号,可提高系统的抗干扰能力。Based on the problem of unreliable zero-crossing detection of rectifier voltage caused by three-phase AC voltage waveform distortion in three-phase rectifier control power supply,the rectification scheme of using hardware comparison circuit to generate pulse is improved appropriately.A rectification scheme of using digital method to generate rectification synchronous signal after FIR filtering of AC signal is adopted.MATLAB simulation shows that the scheme can produce stable and reliable synchronous rectification signal,and improve the anti-interference ability of the system.
