摘要
Abstract
Based on half-bridge LLC resonant converter,a high efficiency LED driver is designed.The LLC resonant convert-er has the merits of both series and parallel resonant converters.The soft switching of the primary switch reduces the switching loss of the power device.Based on the chip TSM103W,a control circuit of the constant current output is designed to reduce the luminous decay of LED light. A prototype converter with input voltage ranging of 400V,an output voltage of 12 V and an output current of 5.5A is built to verify the correctness of the theoretical analysis.关键词
