The design of a hybrid DC/DC converter for LED lighting system using a single switch

Abstract

A novel hybrid Luo-Cuk converter designed for LED lighting systems combines elements from both Luo and Cuk topologies. By integrating the input branch of both topologies, the converter, employing a single switch, can generate two distinct types of outputs simultaneously. One output follows a Luo-type, while the other adopts a Cuk-type . Through a series connection of the outputs from Luo and Cuk topologies, the voltage gain of the converter has been notably enhanced. The converter's output can be effectively regulated using a single controller. To validate the consistency between the topology's performance and theoretical analysis, simulation and prototype results have been provided.
