HIGH POWER FACTOR CONTROL METHOD OF CONVERTER CONSIDERING THREE-PHASE UNBALANCE

摘要

PROBLEM TO BE SOLVED: To provide a high power factor control method of a converter where three-phase unbalance is taken into account by multiplying the average value of impedance in each phase of an unbalance circuit and adding a desired zero-phase voltage.;SOLUTION: In the high power factor control method of a converter where three-phase unbalance for generating a voltage by multiplying an instantaneous current and its 90° phase lag component by a circuit impedance is taken into account, average value of impedance in each phase of an unbalance circuit is multiplied and a desired zero-phase voltage is added.;COPYRIGHT: (C)2007,JPO&INPIT
