Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

And when you work with one, you have to know that any part of the circuit can be at mains voltage. Now read on to see why! A transformerless power supply (TPS) is basically just a voltage divider ...

Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power ...

Bicker Elektronik's Cincon LFM550S AC/DC power supply series offers 550 W of power in an ultra-slim 1-inch low-profile design ...

These could be batteries, solar panels, or a power supply connected to the mains - anything that can provide power to our circuit. A wire from the cell can then be connected to a component like a ...
