Application of Cuk Converter for Capacitor-Less Electrolytic on the Light-Emitting Diode Driver with Artificial Neural Network

Abstract

The use of electrolytic capacitors in the LED driver can affect the lifetime of the LED. But eliminating electrolytic capacitors causes an unstable load power that is unsafe to operate because there are flickers that will cause damage to the eyes. Therefore, there is a need for a bidirectional converter for decoupling power and additional control for setting the switching, so the ability to LED still constant. The control effect uses the Artificial Neural Network (ANN) method to select the switch state on or off in the bidirectional converter. Finally, the result simulations of the output system 92.4 Watt. Useful for verifying the feasibility of the proposed topology and control strategy.
