This paper proposes a resonant switched capacitor-based converter to driver high power light emitting diodes (LEDs). Unlike the traditional switched capacitor based one, the proposed converter uses an inductor to avoid the forced charging and discharging operation reducing stress current in circuit. The proposed converter provides inherent power factor correction (PFC) and the switched capacitors...
This paper proposes a switched capacitor-based converter to drive high-power light-emitting diodes (LEDs). In contrast to conventional constant current dc drivers, the current pulse is provided by a switched capacitor. The proposed approach differs from the traditional switched-capacitor-based one, because it uses a small inductor to improve the switching behavior of the converter. Based on the charge...
