| 摘要: |
| 论述了单开关三相升压式功率因数校正器的工作原理，给出了正器的三相输入电感电流不连续导通模式（ＤＣＭ）一个必要条件，及由此产生的二个具体条件；分析了单开关三相功率因数校正器的可控性，提出了单开关三相功率因数校正器的临界条件法和间断时间控制法。仿真结果表明这二种控制方法都能取得较好的控制效果。 |

| Abstract: |
| It studies the working principle of single switch three phase boost power factor corrector,given out the necessary condition and the two concrete conditions of the three phase input induce current's discontinuous conduct mode(DCM),analyzed the controllable ability of single switch three phase power factor corrector,provided the critical condition control method and discontinuous time control method of the corrector.The simulation resolution presents these control methods can achieve good control affection. |
