Self-Driven AC-DC Synchronous Rectifier for Power Applications

IP Title
Self-Driven AC-DC Synchronous Rectifier for Power Applications
Summary

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 bridge. This technique can be extended from single-phase to multi-phase systems. The new circuit can replace general purpose diode rectifiers.
