I found a good article by chance today which finally clearly explains the pros and cons of each type and wanted to share. We know that MOSFET rectifiers are more efficient and run cooler, but why is that? The difference is in voltage drop Look here: https://en.wikipedia.org/wiki/Active_rectification http://www.thetaeng.com/designIdeas/FETBridge.html http://www.learningelectronics.net/circuits/power-mosfet-bridge-rectifier.html https://www.edn.com/mosfets-increased-efficiency-in-bridge-rectifiers/
