Title:
電力変換装置
Document Type and Number:
Japanese Patent JP6735827
Kind Code:
B2
Abstract:
Voltage commands of respective phases are substantially equally shifted in such a way that a maximum-phase voltage command coincides with the maximum value of a PWM carrier signal and are compared with the PWM carrier signal, so that a voltage is controlled; in addition to that, a current detection value corresponding to the phase where the lower-arm switching device is turned on is corrected based on a current detection value corresponding to the phase where the upper-arm switching device is turned on.
