High frequency inverter with power-line-controlled frequency modulation
TL;DR: In this article, an electronic high frequency supply, such as a lamp ballast, having a full-wave rectifier, a storage capacitor charged to a voltage greater than the peak of the rectifier output, and an isolating diode between the rectifiers and the storage capacitor, is presented.
Journal ArticleDOI
Small signal equivalent circuit modeling of resonant converters
TL;DR: In this paper, a general analytical procedure is presented for the equivalent circuit modeling of resonant converters, using the series and parallel converters as examples The switched tank elements of a resonant converter are modeled by a lumped parameter equivalent circuit The tank element circuit model consists, in general, of discrete energy states, but may be approximated by a low frequency continuous time model.

High power electronic ballast with an integrated magnetic component
Chin Chang,Adan F. Hernandez +1 more
TL;DR: In this paper, a high power electronic ballast for operating one or more discharge lamps includes a power factor correction high frequency SEPIC converter input stage in cascade with an output stage made up of a half-bridge resonant converter.
Journal ArticleDOI
A nonlinear resonant switch
TL;DR: In this article, the buck, boost, and buck-boost nonlinear resonant switch converters are presented, and an approximate analysis is outlined, and transistor peak-voltage and current stresses are shown to be much lower than those of linear resonant switches.
Patent
Power factor correcting circuit
TL;DR: In this article, an electronic circuit arrangement for operating a discharge lamp, having a full-wave rectifier, a storage capacitor charged to a voltage greater than the peak of the rectifier output, and an isolating diode between the rectifiers and the diode was presented.
