摘要
提出了一种数字化倍频式脉宽调制器，并讨论了其实现方法．该方法可减小开关放大器的开关损耗，并使开关放大器的性能得到改善，因而给较大功率的直流伺服系统的设计带来方便．
A digital double-frequency pulse width modulators is advanced and its realizationis disussed. The mothods used can reduce the swiching lossess and improve the performanceof swiching circuit resulting,thus ,in convenience of designing more powerful DC serro-sys-term.
