Abstract :
The possibility of parallel operation of DC-DC power converters with synchronous rectifiers (SRs) is investigated. It is found that, under certain circumstances, self-exited oscillation may occur in parallel-connected DC-DC power converters with self-driven SRs. The cause of this phenomenon is studied. An experimental circuit is built to verify that this problem can be solved by using control-driven SRs
