Title:
INVERTER CONTROL DEVICE AND CONTROL DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/076429
Kind Code:
A1
Abstract:
The present invention performs suitable fail-safe control while suppressing excessive increase in current for charging a DC power source or in DC link voltage, when a failure has occurred in a rotating electric machine drive unit. This inverter control device selectively performs: active short circuit control (ASC) of either upper stage side active short circuit control which turns on upper stage side switching elements of arms for all plural phases or lower stage side active short circuit control which turns on lower stage side switching elements of the arms for all the plural phases; and shutdown control (SD) which turns off all switching elements. The inverter control device performs the active short circuit control (ASC) or the shutdown control (SD) in accordance with a modulation control system that has been running when a failure has occurred in the rotation speed of a rotating electric machine or in the rotating electric machine drive unit.
