| Abstract: | The simulation and analysis of Zeta converter based Light Emitting Diode (LED) driver in open loop and closed loop configuration has been considered in this paper. The Zeta converter maintains near unity power factor on LED load of 100 W. The zeta converter with reduced control circuitry is used in this work for obtaining the benefit of less cost and small size. Pulse width modulation technique is used for generating gating pulse for the converter to regulate the output voltage with improved power factor and reduced total harmonic distortion (THD).The open loop and closed loop operation of zeta converter based LED drive are compared based on the input power factor, current THD and efficiency. |
