  • Patent number: 10483949
    Abstract: A driving circuit for driving a power switch. The driving circuit and the power switch are collaboratively defined as an equivalent circuit. The equivalent circuit includes a first equivalent capacitor corresponding to an input capacitor of the power switch, an equivalent inductor, and a second equivalent capacitor corresponding to a parasitic parameter of at least one driving switch. In the charging procedure or the discharging of the first equivalent capacitor, a change amount of charges in the first equivalent capacitor while a voltage of the input capacitor is changed from a voltage corresponding to no inductor current to a set voltage is larger than or equal to a change amount of charges in the second equivalent capacitor while the voltage of the input capacitor is changed from the voltage corresponding to no inductor current to a steady voltage.

  • Publication number: 20170104419
    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.

  • Publication number: 20160300659
    Abstract: A power module includes a magnetic component and a switch component. The magnetic component includes a magnetic core, and a winding disposed in the magnetic core. An end of the winding forms a pin of the power module for electrically connecting to an external circuit. The switch component is electrically connected to the magnetic component. An I/O pin of the power module may be formed from an end of the winding, such that a bonding/contact resistance of connecting the power module to the external circuit can be reduced.
