Led Street Lights Based on Dc-Dc Converters of Modular Drives

Abstract

This paper proposes a led street lights based on dc-dc converters of modular drives to save energy and if one of the coverters get damaged other converter doesn't get comporise so the LED does'nt stop working and by using this method the LED doen't get damage and increase life-period.In this paper, Light Emitting Diode (LED) electric light unit for street lights based on DC-DC converters were proposed. The driver consists of two modules which are basically converters that are DC-DC type. The foremost in position is a Buck-Boost converter which is obligated to decrease total harmonic distortion (THD) and the second module which is obligated for decreasing the voltage which leads to the control of power. These two converters operate in Discontinuous Conduction Mode(DCM), to construct the system in opposition to failure. Each circuitry contributes their individual LEDS if any of the converters is malfunctioned the system cannot be completely failed. In this paper the input ac supply of 127V is rectified and the rated power of 50 W are performed .
