Abstract : a simple and high - performance brushless dc generator consisting of a controlled rectifying circuit and permanent magnet square wave motor is presented 文摘:提出了一種可控整流電路,它與永磁方波電機(jī)聯(lián)合構(gòu)成一種簡(jiǎn)單、高性能的無(wú)刷直流發(fā)電機(jī)。
At the same time , the control circuit must realize power regulating of the rectifying circuit and the inverter circuit and keep some parameters impervious to the interferer . this paper has researched high frequency solid induction heating power supply 同時(shí),控制電路必須對(duì)整流電路、逆變電路等系統(tǒng)主電路部分進(jìn)行功率控制,使在各種擾動(dòng)下維持系統(tǒng)各參量不偏離其設(shè)定值。
The rectifier scheme that direct current supplying with power electronic equipment is obtained by alternating current being rectified is widely applied in power electronics field . however , the rectifying circuits result in input current distortion , input power factor greatly decrease 從電網(wǎng)獲取交流電經(jīng)整流后為設(shè)備提供直流電是電力電子技術(shù)中應(yīng)用極為廣泛的一種整流方案,然而由這種整流方案設(shè)計(jì)的電路使輸入電流產(chǎn)生嚴(yán)重的畸變,其諧波電流嚴(yán)重污染了電網(wǎng),輸入端功率因數(shù)大大下降。
