A power converter includes a carrier, a first electronic component, a second electronic component, and a connection part. The first electronic component is disposed on the bottom surface of the carrier. The second electronic component is disposed on the top surface of the carrier. A first terminal of the connection part is coupled to the top surface or the bottom surface of the carrier. A second terminal of the connection part is a bonding pad and attached to the first electronic component's surface apart from the carrier. The carrier is disposed at ⅓ to ⅔ of a height of the power-converter. The connection part is fabricated by mechanical support of the first electronic component.
