“…Wang et al [21] propose a dc-dc resonant converter for powering LEDs. In [22,23], a class-D resonant converter with zero-voltage switching (ZVS) is proposed for outdoor applications. Driver circuits are proposed for multiple LED string applications based on full-bridge dc-dc resonant topology in [24,25].…”

This study presents a light emitting diode driver circuit topology based on a full-bridge configuration with dimming control. It is more suitable for high power lighting loads. The proposed configuration has advantages of zero-voltage switching, reduced component count and high efficiency. It can power multiple lighting loads. Operation of the proposed circuit configuration is explained in detail and it is validated through simulated and experimental results on the 145 W experimental prototype with dimming control.

“…Phase-modulated (PM) series resonant converters (SRCs) [5,6] are widely used for dc-dc power conversion as they offer ZVS of full-bridge (FB) MOSFETs and ZCS of rectifier diodes. These converters are traditionally operated in continuous conduction mode (CCM) [7,8], typically above resonant frequency, to guarantee ZVS of FB switches. Since CCM operation of SRC (CCMSRC) stipulates nearly sinusoidal state variables, conventional fundamental harmonic approximation (FHA) technique [10] is used to derive the voltage conversion ratio (A v ).…”

This paper proposes an analytical approach to derive voltage gain for phase-modulated dc-dc series resonant converter (SRC) operating in discontinuous conduction mode (DCM). The conventional fundamental harmonic approximation technique is extended for a non-ideal series resonant tank to clarify the limitations of SRC operating in continuous conduction mode (CCM). The DCM analysis is described in a normalized form defining appropriate base quantities. The converter is analysed both in time and frequency domain to derive a non-linear algebraic function of diode rectifier extinction angle. The root of this function is numerically determined using MATLAB and used to predict the dc bus voltage. Analytical derivation of critical load resistance is discussed, which indicates the CCM-DCM boundary condition. Experimental results are presented to validate the analysis.

LED technology has been used widely in various applications due to its advantage in term of functionality, high efficiency, low cost, small size and high reliability. In order to improve LED performance and prolong LED's life, High Power LED driver is been developed. LED driver is used to control output voltage by using current mode controlled method. This development of LED driver can increase the LED operation efficiency, provide high voltage protection, decreases the driver size and lastly make possible of user friendly installation. Voltage source is step up by using boost converter as main circuit. In control circuit, current mode controlled is used to regulate output characteristic of High Power LED. LTC 3783 is used as PWM controller to drive the gate and provide pulse signal to the MOSFET. This driver is designed to operate load that consists of 6 units LED each rating of 5 Watt connected in series. Theoretical calculation is made to obtain component specification. The LTspice software is used to simulate the driver circuit by using calculated parameters before move on to hardware implementation. Eagle software is used to design the Printed Circuit Board (PCB). Then, all components are mounted on the PCB which is made of FR4 material. The hardware built is tested experimentally and the output waveform is recorded.
