Synchronous rectification is applied in switched mode circuits for reducing conduction losses in low-voltage and high-current applications. The self-driven AC-DC synchronous rectification technique developed by CityU can be used to fabricate an AC-DC synchronous rectifier that behaves like a diode b.....
