PROBLEM TO BE SOLVED: To provide a power conversion device in which the heat of a switching element of an inverter can be excellently radiated.SOLUTION: A power conversion device includes a switching controller for outputting a stop instruction to drive at least a first inverter out of N inverters and stop driving of at least a second inverter when the effective value of AC current detected by a current detector is not more than a predetermined set value, and a circuit board on which a switching element contained in the first inverter and a switching element contained in the second inverter are mounted. The switching element contained in the first inverter and the switching element contained in the second inverter are arranged to be adjacent to each other in a predetermined adjacent direction on the circuit board.SELECTED DRAWING: Figure 1 |
