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 radio frequency interference suppression circuit that includes a reference ground end, a main power circuit, a driving circuit and an impedance unit is provided. The main power circuit includes a first switch that includes a control end, a first and a second end. A minimal impedance is presented between the second end and the reference ground end. The driving circuit is coupled to the control end and the second end. The first impedance unit is formed between the second end and the reference ground end in a high frequency differential mode loop to reduce a high frequency voltage drop therein. The first switch receives a driving signal from the driving circuit to be turned on or turned off between the first and the second ends accordingly to make the main power circuit converts a first power signal to a second power signal.
