Design and implementation of zeta converter for LED driver applications

Abstract The objective of this study is to analyze the design and operation low power, stand-alone active led driver applications. system powered by solar PV panels with a maximum input power 125 W. chosen converter supports continuous conduction mode. device seems have switching frequency 20 kHz. duty cycle controlled MPPT controller, which keeps dc bus voltage constant. employs an incremental conductance method. intention used control at 48 V. preferred verified in both Matlab/Simulink its performance evaluated on hardware prototype 25 While module efficiency output dependent irradiation ambient temperature, maximizing while increasing key significance. resulting highly efficient, cost able track faster.
