  • Circuit of reducing power loss of switching device
    Patent number: 7969225
    Abstract: A circuit is provided to reduce power loss on switching. A pair of auxiliary switching devices is switched on before a pair of switching devices. The switching devices are switched on after a corresponding capacitor to the auxiliary switching devices is discharged to zero. Thus, the power loss of the switching devices is reduced.
    Type: Grant
    Filed: February 5, 2010
    Date of Patent: June 28, 2011
    Assignee: Atomic Energy Council-Institute of Nuclear Energy Research
    Inventors: Yuan-Hsiang Ho, Yung-Ruei Chang, Jih-Sheng Lai
