Abstract :
The low-loss self-driven rectifier we developed requires no external power supply and uses a novel CMOS control circuit that generates the power MOSFET drive signal by boosting the intrinsic body diode voltage drop. The rectifier significantly improved conduction loss - a 47% decrease from intrinsic-body-diode-based conduction loss - during half-wave rectification. It can replace with a common diode for a rectifier.
