چکیده
Electric vehicles contain various types of light emitting diode (LED) devices. A significant twice-line-frequency ripple current is usually produced in a conventional offline LED driver with high power factor. In this paper, flicker-free based on isolated Cuk converter integrated magnetic technique proposed. Two inductors and transformer are combined into one core to eliminate the wave as much possible. With time domain analysis electrical circuit circuit, operation principle, operational waveforms, transfer function analyzed detail. Finally, experimental results from 30 W laboratory prototype supplied by 220 V grid validate effectiveness proposed driver.

Design of Flicker-Free Electrolytic Capacitor-Less Ac-Dc Led Driver
The life of LED driver is mainly dependent on the component used in it. Elimination of electrolytic capacitor is done so that the life of LED driver will increase, if an ac-dc LED driver with power factor correction control is used than the output will be a pulsating current for driving the LED. Since the pulsating current will introduce light flicker that varies double the power line frequency...
