LED Application Design Guide Using Half-Bridge LLC Resonant Converter for 100W Street Lighting

AN-9729 — LED Application Design Guide Using Half-Bridge LLC Resonant Converter for 100W Street Lighting

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of the non-isolation DC-DC converter to control the LED current and the light intensity, the conventional PWM DC-DC converter has the problem of low-power conversion efficiency. The half-bridge LLC co...

A Single-Stage LED Driver Based on Interleaved Buck-boost Circuit and LLC Resonant Converter

A single-stage LED driver based on interleaved buck-boost circuit and LLC resonant converter is proposed. The buck-boost circuit and LLC resonant converter are integrated by sharing switches, which can decrease the system cost and improve system efficiency. The input voltage of the buck-boost circuit is half of the rectified voltage, and two buckboost circuits are formed with the two half-bridg...
