Abstract

The conventional structure of the renewable street lighting systems required two converters. A buck converter used for battery charging during the day, and a boost converter used to supply power to the lighting system from the battery during night. Combining the two converters is desirable as both cost and size are reduced. In this paper, a novel structure of a modular interleaved DC/DC converter with PWM/PID control technique for renewable street lighting system is presented. During the day, the proposed converter works in a buck mode and is used to charge the battery. at night, the converter works in a boost mode to provide power to the lighting system. Analysis of the converter is carried out in order to achieve the required system stability and to improve its dynamic performance. The operating principle and boundary conditions are discussed too. All the advantages of interleaving technique, such as higher efficiency and reduced ripple for voltage/current, are also maintained. The simulation results are presented to show the performance of the proposed converter.
