Useful for electronics hobbyists, this linear workbench desktop power supply circuit converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

Hurricane and wildfire seasons are underway, and they appear to be getting longer and more severe in recent years. In response to this, portable generators and power stations have become critical ...

How to replace MOSFETs with load switches, and the impact of on-resistance. Swapping out diodes with ideal diodes, and the use of ideal-diode controllers. Why replacing fuses and resettable fuses with ...
