Document Type and Number:
Japanese Patent JP5499850
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a discharge controller for an inverter that discharges electric charge accumulated in the inverter with simple circuit constitution.SOLUTION: A discharge controller is mounted on a vehicle, and discharges the electric charge accumulated in an inverter 1 including a switching element 8 of an upper arm and a switching element 9 of a lower arm. The discharge controller is characterized in discharging electric charge in the inverter 1 by that the switching element 8 of the upper arm is turned ON/OFF or fixed to ON after the switching element 9 of the lower arm is fixed to ON when the vehicle is abnormal or an abnormality of the vehicle is predicted. It is preferred that when the switching element 8 of the upper arm is turned ON/OFF or fixed to ON, it is set to be lower than a drive control voltage of a motor or DC-DC converter driven by the inverter 1.
