| Description | Journal: Iop Conference Series: Materials Science and Engineering Traditional lighting emitting diode (LED) driving circuits generally use electrolytic capacitors as the filter component, and the lifetime of electrolytic capacitor becomes the main limiting factor for extending the lifetime of LED lighting. Therefore, this paper proposes a new current-source 5-level DC-DC circuit to construct the LED driver. It can not only remove large electrolytic capacitors to improve the service life of LED driver, but also the high input power factor can be achieved by 5-level PWM modulation. Finally, the feasibility and effectiveness of such LED driver are verified by simulation results. |
