The adapter PAE sources is a flyback converter. https://en.m.wikipedia.org/wiki/Flyback_converter
Flyback is a buck-boost DC/DC converter where the inductor is split into a transformer to allow a big voltage change (340v in to 12v out) and provide galvanic isolation for safety. There’s a controller which adjusts the pulse width and period of the MOSFET switch that charges the primary to regulate the output voltage under changing input voltage and load current. 73 Josh W6XU Sent from my mobile device > On Jul 31, 2019, at 2:14 AM, David Wilcox via Elecraft > <[email protected]> wrote: > > Thank you all for the information.
