Abstract: A power converter device includes a first current level, a second current level, a first magnetic layer and a second magnetic layer. The first current level and the second current level are used to load a current loop which has AC current component. The current loop includes a power element module and a conductor coupled to the power element module. The power element module includes at least two electrodes. Voltage among the at least two electrodes is AC voltage. AC current magnitudes of the at least two electrodes are substantially equal and in the opposite direction. The first magnetic layer and the second magnetic layer are used to load a magnetic loop which includes AC magnetic flux component. The first magnetic layer and the second magnetic layer are disposed in two opposite sides of the first current level.

Abstract: A power converter device includes a power element module, a conductor, and a magnetic-conductive assembly. The power element module includes at least two electrodes and a power semiconductor unit. Voltage among these electrodes is AC voltage. The power semiconductor unit includes at least one pure die, and the pure die includes plural surfaces. The surface which occupies the most area of the pure die is the pure die surface. The conductor is coupled to the power element module. A current loop forms between the power element module and the conductor. A magnetic loop forms in the magnetic-conductive assembly. The magnetic-conductive assembly includes a chamber. The current loop passes through the chamber and intersects the magnetic loop to form inductance which the current loop needs. A part of the power element module is disposed in the chamber.

Abstract: 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.
