| 摘 要： | 提出了一种由两个单相Sepic电路并联构成的三相功率因数校正器.三相电经工频变压器形成两个相位正交的交流输入,从而避免了3个单相并联时产牛的中性点浮动,并能减小三相之间的耦合干扰.使两个单相PFC电路模块化,输入电流波形接近正弦单位功率因数,消除电流谐波的2次分量,使开关管承受较小的电压及电流应力.仿真和实验证明该系统具有高功率因数、低电流畸变、较强抗干扰能力及高可靠性的特点.

| Abstract: | A new three-phase power-factor-correction (PFC) scheme is discussed using two single phase power-factor-correction circuit parallel connected.Two phase orthonormal voltage is produced by means of a auto transformer from a three phase input,fluctuation of neutral point by three single phase power-factor-correction circuit parallel connected is canceled,coupling interference is reduced among three phases,two single-phase power-factor-correction modularized circuits is made,input current wave sine with unity p... |
