MOSFET heat
With heated beds becoming more and more standard, MOSFETs are used to switch currents in excess of 10 Ampéres, sometimes 15 A. While MOSFETs exist which claim to be capable to switch much higher currents, it has been shown they require a careful integration into the electrical design of the electronics. To get to the bottom of this, I've done a few measurement series', measuring heat development of a MOSFET in different configurations.
