PROBLEM TO BE SOLVED: To obtain a power conversion device for maintaining the effect of reduction in processing cost and the like, improving performance, and reducing size and cost or the like.;SOLUTION: The power conversion device includes a sensor 5 that detects a rotor of a motor 8, an inverter (HVIC 9 and switch elements 12 to 17) that controls the number of revolutions of the motor 8, and a peripheral circuit (gate signal generation circuit 6) that controls the inverter. The peripheral circuit is integrally structured. The switch elements 12 to 17 provided in the inverter are surface-mounted switch elements each configured in different packages.;COPYRIGHT: (C)2010,JPO&INPIT
