A novel zero-voltage switching full-bridge (NZVSFB) converter designed for multiple load LED driver applications is introduced in this paper. Four LED lamps are involved in this configuration, with Lamp-2, Lamp-3, and Lamp-4 being powered by a full bridge converter, and Lamp-l being directly connected in series with the battery source. The efficiency of the system is increased since the power provided to lamp-l comes directly from a battery source, eliminating the need for any power processing stage. The major claims of the proposed NZVSFB converter are low component count/lamp, enhanced efficiency, zero voltage switching (ZVS) of all the switching devices, ripple free current and equal current sharing. The interleaved technique utilized in inductor design aims to mitigate the adverse effects of ripple currents on LED performance and circuit reliability by reducing their magnitude and ensuring more stable operation. The steady state operation of the proposed NZVSFB converter is discussed in detail and the effectiveness of the circuit is verified in MATLAB Simulink environment.
