| Abstract |
Active Diode is a type of Current-driven
synchronous rectifier (CDSR) with energy recovery current
sense which can replace rectifier diode in any converter
regardless of the topology. This paper presents extended
analysis and practical considerations of the CDSR from
sensing current to driving MOSFET. Hysteresis gate drive
buffer so introduced can further improve the operating
frequency range from line frequency of 50Hz up to several
hundred KHz. It reduces losses and size of the current
transformer, and gives robust operation even when the output
is short circuit. |
