Rik W A A DeDoncker, James P Lyons: Auxiliary quasi-resonant dc link converter. General Electric Company, Jill M Breedlove, Marvin Snyder, December 15, 1992: US05172309 (70 worldwide citation)

An auxiliary quasi-resonant dc link (AQRDCL) converter is employed to achieve soft-switching in an inverter coupled to a dc supply via a resonant dc link circuit. The resonant dc link circuit generates a quasi-resonant voltage to the inverter via a resonant bus. The dc link circuit includes upper an ...
