| description | LED (light-emitting diode) drivers with the non-resonant DC-DC converters produce higher current and voltage ripple
than the resonant converters. The resonant converter-based LED drivers provide low cost, high efficiency, enhanced
soft switching capabilities, and simple construction. Therefore, this research work is motivated to propose a hybrid
resonant converter to power the LED. The proposed modified hybrid resonant with valley-fill converter is built
by removing the capacitors across the switches and the output diode is replaced with a valley-fill circuit in
the conventional hybrid resonant converter. With the valley-fill circuit, the switches and the diode are
subjected to reduced stress, reduced flicker, and improved efficiency. The modified Hybrid resonant
converter with valley-fill circuit LED driver’s performance parameters are compared with existing
resonant converter topologies in terms of component count, current stress, voltage stress across the
switch and output diode, LED voltage ripple, current ripple, and efficiency. A 10 W, 24 V laboratory
prototype of modified Hybrid resonant converter with valley-fill circuit LED driver is developed,
and the simulation results are validated. |
