【 摘 要 】

Light emitting diode specifically White LED has gain a lot of attention from both academics and industrial sector due to its high efficiency, environmental friendly, and long lifecycle. This is a feasible alternative for conventional bulbs and tubes in domestic, industrial and commercial lighting. However, implementation of this new source requires various parametric regulation. This proposed single stage isolated zeta converter (SS-IZC), with power factor correction maintains constant output for the load of 36 Watts LED, and follow the IEC61000-3-2 standard. The proposed SS-IZC is operating in DCM and controlled with PWM (Pulse width modulation), for power factor improvement and low THD, and obtain more than 0.9 power factor and THD less than ten percentages.
