<P>PROBLEM TO BE SOLVED: To provide a small-sized, reliable power conversion device. <P>SOLUTION: The power conversion device 1 includes an inverter unit and a DC-DC converter unit. The power conversion device includes a power module 19, having multiple switching elements, a coil 10 and a capacitor 11 for transforming and smoothing voltage outputted from the switching elements, and an enclosure 4 for installing the coil 10 and the capacitor 11. The power conversion device is so constituted such that a heat shield wall 20 is provided between the coil 10 and the capacitor 11, and the coil 10 is sealed with a heat conductive insulating material 21. <P>COPYRIGHT: (C)2008,JPO&INPIT |
