Driver Circuits for Dimming of LED

In this paper, the driver circuits are proposed for Light Emitting-Diode (LED) lamps with a dimming feature. The two different drivers used are flyback converter and forward converter in series with the DC-link. In this paper, the two driver circuits are compared for the controlled output current and voltage. The dimming is achieved by pulse width modulation technique. The variation is observed with the different values of duty cycles. This paper is a comparison between the two driver circuits.
