A power conversion device is connected to a three-phase motor mounted on a vehicle and includes an inverter circuit, a gate drive substrate, and a motor control substrate. In the motor control substrate, when the vehicle is in the non-operation state and a regenerative voltage applied from the three-phase motor to the inverter circuit becomes equal to or more than a predetermined threshold value, a power supply circuit supplies operation power to a control circuit. The control circuit starts when the operation power is supplied from the power supply circuit and outputs gate control signals to a driver circuit of the gate drive substrate, such that regenerative energy according to the regenerative voltage is consumed between the three-phase motor and the inverter circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device","description":"Even in the case in which an overvoltage is generated when a vehicle is in a non-operation state, the overvoltage can be suppressed.
