A Novel Three-phase Power Factor Correction With Digital Control

摘要：

　　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,digitally controlled Power Factor Correction Boost Converters is adapted,input current wave sine with unity power factor suppress the secondary harmonic of input AC side is realized,voltage and low current stresses across each switch are reduced.Simulation and experimental results prove that it can achieve high power factor,low current,good capability of anti-interference and high reliability.
