Document Type and Number:
Japanese Patent JP2019068698
Kind Code:
A
Abstract:
To provide a power conversion device capable of improving heat resistance and heat dissipation and being downsized.SOLUTION: A power conversion device 1 includes a transformer 2, a diode 4 having a body housing a diode element and a pin electrically isolated from the body, and a reactor 3. The pin of the diode 4 is fixed and electrically connected to a primary winding 3c of the reactor 3 by welding. A secondary winding of the transformer 2 is provided with a press-fit portion into which the body of the diode 4 is press-fit, and the body of the diode 4 is press-fit and fixed to the press-fit portion and is in contact with a base 6 via a heat dissipation sheet 5.SELECTED DRAWING: Figure 1
