CURRENT LIMITING DEVICE FOR VEHICLE
First Claim
1. A current limiting device for vehicle connected to a condenser at an input terminal and to a motor generator at an output terminal, comprising:
- a switching portion that passes and cuts off a current from the input terminal to the output terminal;
a reflux portion that is connected to a connection point of the switching portion and the output terminal and supplies the current to the motor generator while the switching portion is cutting off the current;
a current measurement portion that measures the current flowing from the output terminal to the motor generator; and
a current control portion that controls the switching portion to switch ON and OFF according to a current value measured by the current measurement portion,wherein, when the motor generator is rotary driven using electric power of the condenser, the current control portion limits the current to the motor generator by controlling the switching portion to switch ON and OFF in a case where the measured current value is equal to or exceeds a predetermined current value.

Abstract
A current limiting device for vehicle includes a switching portion that passes/cuts off a current from an input terminal to an output terminal, a reflux portion that is connected to a connection point of the switching portion and the output terminal and supplies a current to a motor generator while the switching portion is cutting off the current, a current measurement portion that measures the current flowing from the output terminal to the motor generator, and a current control portion that controls the switching portion to switch ON/OFF according to a current value measured by the current measurement portion. When the motor generator is motor-driven using electric power of a condenser, the current control portion limits the current to the motor generator by controlling the switching portion to switch ON/OFF in a case where the measured current value is equal to or exceeds a predetermined current value.
