Hybrid Switch For Resonant Power Converters

View page
US Patent:
20120057387, Mar 8, 2012
Filed:
Aug 10, 2011
Appl. No.:
13/206846
Inventors:
Jih-Sheng Lai - Blacksburg VA, US
Wensong Yu - Blacksburg VA, US
International Classification:
H02M 7/5387
H03K 17/567
H02M 7/00
H02M 7/537
H03K 17/284
H03K 17/687
US Classification:
363132, 327399, 327434, 363123, 363131, 327403
Abstract:
A hybrid switch comprising two semiconductor switches connected in parallel but having different voltage drop characteristics as a function of current facilitates attainment of zero voltage switching and reduces conduction losses to complement reduction of switching losses achieved through zero voltage switching in power converters such as high-current inverters.

US Patent:
20150263635, Sep 17, 2015
Filed:
May 28, 2015
Appl. No.:
14/724506
Inventors:
- Plano TX, US
Wensong Yu - Blacksburg VA, US
Hengchun Mao - Plano TX, US
Heping Dai - Plano TX, US
International Classification:
H02M 3/335
Abstract:
A multilevel LLC resonant converter comprises a resonant tank connected in series with a primary side of a transformer, a first switch and a second switch connected in series, wherein a common node of the first switch and the second switch is coupled to a mid-voltage point through a first isolation switch and the resonant bank and a third switch and a fourth switch connected in series, wherein a common node of the third switch and the fourth switch is coupled to the resonant tank.
