A novel driving scheme for synchronous rectifier suitable for modules in parallel

This paper presents a driving scheme for synchronous rectifier, which maintains the performance of synchronous rectifier as self-driven, while solves the problem of short circuit when modules run in parallel. In addition, the amplitude of synchronous rectifier driving voltage can be adjusted by usin...

Description
Summary:This paper presents a driving scheme for synchronous rectifier, which maintains the performance of synchronous rectifier as self-driven, while solves the problem of short circuit when modules run in parallel. In addition, the amplitude of synchronous rectifier driving voltage can be adjusted by using the proposed scheme. So, it is more attractive in some occasions that the driving voltage is too high if self-driven is adopted. The principle of operation and the characteristics of the scheme are analyzed and verified on a 36 V/spl sim/75 V input 1.8 V/60 A output experimental prototype, whose size is 1/4 brick and efficiency is above 90% under rating condition.
