Abstract
Official abstract text for this publication.
A control unit controls driving of a motor by controlling a first inverter unit and a second inverter unit, specifically by controlling on/off operations of FETs. The control unit functions as an abnormality detection device. The control unit detects a short-circuit abnormality between a first winding set and a second winding set or between the first inverter unit and the second inverter unit, before starting to control driving of the motor, based on phase current values detected by current detectors when a high-side FET of the first inverter unit and a low-side FET of the second inverter unit are turned on.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotary electric machine control apparatus for controlling a rotary electric machine, which has two winding sets formed of coils corresponding to plural phases, the rotary electric machine control apparatus comprising: two inverter units provided in correspondence to the two winding sets for converting electric power from a power source to the rotary electric machine by turning on and off plural switching elements, which include high-potential side switchin…
