Patent number: 11018596Abstract: 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.Type: GrantFiled: October 4, 2016Date of Patent: May 25, 2021Assignee: DELTA ELECTRONICS, INC.Inventors: Jian-Hong Zeng, Xiao-Ni Xin, Rui Wu, Min Zhou, Hao-Yi Ye

Patent number: 10483949Abstract: 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.Type: GrantFiled: October 24, 2016Date of Patent: November 19, 2019Assignee: DELTA ELECTRONICS, INC.Inventors: Pei-Qing Hu, Jian-Hong Zeng, Hao-Yi Ye
