High-Efficiency Single-Stage LLC Resonant Converter for Wide-Input-Voltage Range

In this paper, a new single-stage half-bridge (HB) resonant LLC converter additionally employing one resonant capacitor and two relays with one package is proposed, compared with a single-stage HB LLC converter. Moreover, a center-tapped transformer is replaced with a coupled transformer. Since the...
