Abstract
A forced discharge apparatus for a high-voltage component may include a component unit connected to a power supply unit through a connector. The forced discharge apparatus may also include a forced discharge circuit connected between the power supply unit and the component unit. The forced discharge apparatus may also include a control unit configured to discharge the component unit through the forced discharge circuit such that a voltage of the component unit becomes below a target voltage in response to a detection that a back electromotive force generated from the component unit when the connector is separated.
Claims15
A forced discharge apparatus for a high-voltage component, the apparatus comprising:
- a component unit connected to a power supply unit through a connector;
- a forced discharge circuit connected between the power supply unit and the component unit;
- and
- a control unit configured to discharge the component unit through the forced discharge circuit such that a voltage of the component unit becomes below a target voltage in response to detecting a back electromotive force generated from the component unit when the connector is separated.
A forced discharge method for a high-voltage component, the method comprising:
- starting a forced discharge to forcibly discharge a back electromotive force, by a forced discharge apparatus, when an occurrence of an interlock is detected according to separation of a connector between a power supply unit and a component unit;
- detecting, by the forced discharge apparatus, whether a back electromotive force occurs at the component unit;
- and
- performing the forced discharge, by the forced discharge apparatus, for discharging a voltage of the component unit to be below a target voltage, in response to detecting the occurrence of the back electromotive force.
