一种低开关电压应力的平顶单端谐振变换器

This article proposes a flat-top single-ended resonant converter (SERC) for wireless charger with the merit of low switch voltage stress, by introducing a parallel LC network in series with the primary switch. A characteristics analysis of the proposed SERC is performed in time domain, obtaining the zero-voltage-switching condition, power transfer capacity expression, and the time requirement to a...
