Drive circuit for power converter
In a control circuit for a power converter applicable to a system including a rotary electric machine, a fail-safe controller performs, in response to determination that there is a failure in the system, a short-circuit control routine that turns on predetermined turn-on arm switches, and turns off...

| description | In a control circuit for a power converter applicable to a system including a rotary electric machine, a fail-safe controller performs, in response to determination that there is a failure in the system, a short-circuit control routine that turns on predetermined turn-on arm switches, and turns off predetermined turn-off arm switches. The turn-on arm switches bare one of (i) upper-arm switches and (ii) lower-arm switches, and the turn-off arm switches are the other of (i) the upper-arm switches and (ii) the lower-arm switches. An on determiner detects a drive state of each turn-on arm switch upon determination that the turn-on is instructed for the corresponding turn-on arm switch, and determines, based on the drive state of each turn-on arm switch, whether the turn-on arm switches are switchable to be on in preparation for a short-circuit control routine performed by a short-circuit controller. |
