Abstract
A power conversion device for driving a load, including a power conversion device main body configured to receive an input of a power supply voltage and to drive the load, and a brake circuit configured to protect the power conversion device main body from overvoltage applied thereto. The brake circuit includes a Zener diode that becomes conductive when the voltage applied to the power conversion device main body exceeds a predetermined value, to thereby suppress the voltage.
