摘要: This paper furnish an input voltage controlled full-bridge inverter based LED driver. A Double-ended forward converter(DEFC) is used along with to regulate the of full bridge for variations in supply voltage. Input sum primary DC and output DEFC. DEFC from source. Supply obtained proposed configuration can be micro grid. Thus operated fixed frequency duty ratio achieve ZVS over wide range variations. Full converter interleaved operation inductor currents ripple free constant current string. In this configuration, power processed by low which doesn't influence significantly, overall efficiency expected high. The circuit analyzed simulation results are presented.
