半桥LLC变换器的谐振驱动技术
Resonant Gate Drive Technology of Half-bridge LLC Converter
摘要
Abstract
A resonant gate driver(RGD)was proposed for the control tubes of the LLC converter. A constant current source driver(CSD)was used for the synchronous rectifiers. The working principle,drive losses and the optimization design of resonant inductance of RGD and CSD circuit were analyzed in detail. For control tubes,the optimum design was the balance between drive losses and turn-off losses;for synchronous rectifiers,the optimum design was the balance between drive losses and body diode losses. At the same time,the prototype of a 1 MHz synchronous rectifier half-bridge LLC was designed and the experimental results are given.关键词
