Abstract

With the technological advancement of LED light sources, their output power has gradually increased. High-power LED light sources require larger heat dissipation components, which put forward higher requirements for the volume of other parts. As an important part of the lighting system, the LED drive circuit can effectively reduce the overall size by improving efficiency and operating frequency. In this paper, a Matrix Resonant Switched-Capacitor topology is proposed to improve the electric power density of LED drive. The design has the ability to be flexibly adjusted according to output requirements. A prototype of the base module with 50W output is made, showing the feasibility of the proposed topology.
