TL;DR: This paper presents a battery impedance analysis when the dc component is considered in the SRC charging, and presents that the CC-CV charging using a slightly larger dc is more suitable for practical applications, since its current stress, charging time, and maximum rising temperature are improved by 2, 9.7%, and 8.5%, respectively.

TL;DR: A simple control method of the half-bridge (HB) LLC converter with one additional switch and capacitor in the primary side is proposed for wide-input-voltage applications with the hold-up time conditions and it can reduce the conduction and switch turn-off losses in thePrimary side, which makes it highly efficient.

TL;DR: In this article, a digital predictive peak current control (PPCC) employing the adaptive slope compensation is proposed, which precisely predicts the peak current reference with the adaptive SLP according to operation regions and load conditions.

TL;DR: In this paper, the authors proposed an interleaved totem-pole bridgeless boost power factor correction (PFC) converter with soft-switching capability, where an inductor is added between two PFC converter units, and by utilizing the energy of the added inductor, all switches can achieve the zero voltage switching.

TL;DR: In this article, a single-stage half-bridge (HB) resonant $LLC$ converter additionally employing one resonant capacitor and two relays with one package is proposed, compared with a singlestage HB $LCC$ converter, where a center-tapped transformer is replaced with a coupled transformer.
