Title:
電力変換装置
Document Type and Number:
Japanese Patent JP5623994
Kind Code:
B2
Abstract:
A power converter includes an inverter, a contactor for connecting a battery to the inverter in order to supply DC power from the battery to the inverter and for disconnecting the battery from the inverter in order to stop an operation to supply the DC power from the battery to the inverter, a smoothing capacitor connected in parallel to the battery through the contactor, a discharge circuit that is provided with a discharge resistor and a switching device connected in series to the discharge resistor and is connected in parallel to the smoothing capacitor to discharge electric charge from the smoothing capacitor, a voltage measurement circuit, a voltage-dividing circuit for dividing the voltage across the terminals of the smoothing capacitor to generate a partial voltage to be input to the voltage measurement circuit and a control circuit of the switching device.
