A novel half-bridge LLC DC-DC Resonant Converter for high power DC power supply is presented in this paper. The design consideration of resonant tank circuit paramerters are presented. The DC gain characteristics of the proposed converter is analyzed from its complex DC gain equation. First the performance of the converter is analyzed through simulation. The proposed converter operate with higher...
This paper proposes a high efficiency driving circuit for multiple high-brightness light emitting diode (HB-LED) lamps with dimming feature. A high-frequency half-bridge series resonant inverter is adopted as a current driver. By appropriately controlling the frequency of the active switches and the resonant tank, the lamp currents can be regulated effectively. On the other hand, the LED lamps can...
