摘要: The authors have previously proposed two methods for evaluation of the iron loss AC filter inductor used in a pulse width modulation (PWM) inverter. first is map method based on loss-map magnetic materials, which can be to calculate and predict without an actual circuit. other analyzer (ILA) method, directly measure every one-switching Effectiveness both was already verified single-phase PWM inverter, but has not yet been three-phase In this paper, accuracy calculated by it found that calculation error arises especially inverters. error, however, reduced introducing revised process method.
