Power converting device
First Claim
1. A power converting device, comprising:
- a power element module, comprising;
at least two electrodes, wherein voltage among the at least two electrodes is AC voltage; and
a power semiconductor unit, comprising;
at least one pure die including a plurality of surfaces, wherein the surface which occupies a most area of the at least one pure die is a pure die surface;
a conductor coupled to the power element module, wherein a current loop forms between the power element module and the conductor; and
a magnetic-conductive assembly, wherein the magnetic-conductive assembly comprises a magnetic core, and a magnetic loop forms in the magnetic core of the magnetic-conductive assembly, wherein the magnetic-conductive assembly comprises;
a chamber, wherein the current loop passes through the chamber, and intersects the magnetic loop to form inductance which the current loop needs, wherein a part of the power element module is disposed in the chamber;
wherein an included angle between the pure die surface and an axis of the current loop is equal to 0 degrees in a one configuration and may be greater than 0 degrees but less than or equal to 45 degrees in another configuration.

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.
