A power conversion device according to one or more embodiments may include: a microcomputer; and an output circuit controlled by the microcomputer, including an output unit that converts an input power into a predetermined power and outputs the predetermined power, an internal power source that supplies a power source to the microcomputer, a driver that drives the output unit by a signal from the microcomputer, and a microcomputer stop transition unit that, when an operation of the power conversion device is stopped, outputs a microcomputer stop signal to the microcomputer and causes an operation of the microcomputer to transition to a stop state. In one or more embodiments, after the microcomputer stop transition unit causes the operation of the microcomputer to transition to a stop state, the microcomputer or the output circuit may stop an output of the internal power source.
