This type of linear power supply has an extremely simple circuit consisting of a transformer, bridge rectifier, and capacitors.

As you can see from the circuit diagram, 'Dual Variable PSU.pdf', it is simple and based upon two adjustable linear voltage regulators, an LM317 and the negative LM337 regulator both adjusted via a ...

PartSim is a web-based application that allows you to create and simulate electronic circuits online. In this article we are going to examine and simulate the behavior of a simple power supply.

Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components.

On one end of the twisted pair is a power supply and decoder circuit, which sends 9 volts up the line to power the PIC sensor.

This article explains a simple method for designing loop compensation in current-mode controlled switch-mode power supplies.
