Proceedings ArticleDOI
Resonant switches - Topologies and characteristics
TL;DR: In this article, the concept of resonant switch was proposed to overcome the obstacles of higher switching stresses and switching losses in conventional switching converters, by incorporating additional Land C elements to shape device current and voltage waveforms, the desired zero-current switching property can be realized.
Journal ArticleDOI
Conducted EMI Mitigation Techniques for Switch-Mode Power Converters: A Survey
Krishna Mainali,Ramesh Oruganti +1 more
TL;DR: In this article, a detailed classification and review of various noise mitigation techniques currently available in literature is presented, based on two criteria: reduction of the noise after generation and reduction of noise at the generation stage itself.
Journal ArticleDOI
Quasi-Resonant Converters-Topologies and Characteristics
TL;DR: In this article, a quasi-resonant switch with inductor and capacitor elements to shape the semiconductor switch's current waveform is proposed. And a new host of quasi-reonant converter circuits have been derived, which can be operated in the megahertz range.
Journal ArticleDOI
Resonant Power Processors, Part I---State Plane Analysis
Ramesh Oruganti,Fred C. Lee +1 more
TL;DR: In this article, the steady-state and transient characteristics of a series resonant converter were investigated using stateplane techniques in conjunction with piecewise linear analysis. But the state-plane technique was not applied to the case of a single-input single-output (SISO) converter.
Journal ArticleDOI
A Low Cost Flyback CCM Inverter for AC Module Application
Yanlin Li,Ramesh Oruganti +1 more
TL;DR: In this article, an open-loop control of the secondary current, based on feedback control of primary current, is proposed in order to bypass the difficulties posed by the moving right half plane zero in the duty cycle to secondary current transfer function.
