Continuous current source driver
This chapter presents a two-channel current source driver (CSD) with the continuous current, which can provide two symmetrical drive signals for driving two metal oxide semiconductor field-effect transistors (MOSFETs). The proposed drive circuit can recover most of the driving energy. It can also reduce the switching loss significantly. The proposed CSD can be used to drive the synchronous rectifier (SR) in a current doubler or full-wave rectifier. It can also be used to drive the primary MOSFETs in push-pull converters.
