An efficient full-bridge DC-DC converter with zero-voltage switching for LED lighting applications

摘要

In this paper, a soft switched LED driver is proposed for street light applications. It is suitable for high power lighting, as this driver uses a full bridge topology. It operates with ZVS and provides high efficiency. It offers the features of dimming control and constant peak current regulation in LED loads. This configuration is suitable for Solar PV fed LED lighting application. The detailed description and analysis of the circuit operation and simulation results are presented.
