While secondary-side synchronous rectification in resonant half-bridge topology is not uncommon, its implementation has not been easy. A novel control scheme precisely turns on and off the secondary-side synchronous rectifier MOSFETs to achieve rectification that emulates a Schottky-diode rectifier, minimizing switching losses and optimizing conver...
The standards require that new TVs sold in California consume 49% less electricity by 2013. [...]
