摘要

There is provided a current tracking PWM control circuit that directly generates PWM signals such that inverter output currents id, iq track PWM current references id**, iq**, using the results of comparison of the inverter output currents id, iq and PWM current references id**, iq**, in which, if current references id*, iq* exist, the result of adding the original current reference iq* and a correction signal iqC*, obtained by amplifying the deviation (iq*-iq) of the current reference iq* and iq, is used as the PWM current reference iq** on the q axis side for performing current control, but, in respect of the d axis side, the original current reference id* is used directly as the PWM current reference id** for performing current control.
