Effective testing of a power supply requires far more than just connecting it to a PC and using a $10 multimeter to check the voltage rails. At the very least, it requires specialized (and very expensive) equipment. At this point, most people that actually know a few things about PSUs w...
3) if there is a larger voltage on one of the combinations check if it can source current, so connect something that draws a few mA with the measured voltage (big enough resistor and Amp meter in between) and see if the voltage persists and with what current (then you know it can del...
A boost converter is a kind of SMPS or switch mode power supply which fundamentally works with two active semiconductors (transistor and diode) and with a minimum of one passive component in the form of a capacitor or an inductor or both for greater efficiency. The inductor here basically is ...
