Title:
電力変換装置およびその制御方法、電動パワーステアリングの制御装置
Document Type and Number:
Japanese Patent JP6381662
Kind Code:
B2
Abstract:
Provided are a power conversion device, relating to control of detecting a bus current in operation, and capable of acquiring an average current through a small amount of calculation and being implemented by an inexpensive microcomputer. A variation in a winding current flowing through a multi-phase winding of an AC rotating machine, namely, a phase current, is small at a timing at which voltage vectors on both sides of an axis having a larger inductance out of d and q axes of the AC rotating machine are output. Thus, switching signals are generated at timings at which the voltage vectors on both sides of the axis having the larger inductance out of the d and q axes are output, and the bus current is detected in accordance with the switching signals, thereby acquiring a value close to an average of the winding current.
