Abstract
A control system includes an electronic control unit. The electronic control unit is configured to execute three-phase ON control such that two transistors connected in parallel to the first transistor are switched ON when a condition i) is satisfied, The first transistor is one of the transistor of the six transistors and in which the short-circuit fault has occurred. The condition i) is that a recovery loss of a first diode in which a reverse recovery current is generated is estimated to be smaller than a recovery tolerance.
Claims5
A control system for an inverter, the inverter including six transistors and six diodes,
- the control system comprising:
- an electronic control unit configured to execute three-phase ON control such that two transistors connected in parallel to a first transistor are switched ON when a condition i) is satisfied, the first transistor being one of the six transistors and in which the short-circuit fault has occurred,
- i) a recovery loss of a first diode that is one of the six diodes in which a reverse recovery current is generated is estimated to be smaller than a recovery tolerance.
