When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable pr… ...

2. Designers need to make power, speed, and resolution tradeoffs in the analog domain. Many pure analog circuits have been implemented to save power and allow for low-supply-voltage operation by ...

In addition to the natural output capacitance of the power supply, you might add a series inductor and another filter capacitor to further reduce output noise (Fig. 3). The inductor passes dc ...

Here is a Power Supply Guard circuit that can be used as a protective device in power supply boxes. This type of Spike protection circuit is present in the multi socket switch boards used to connect ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

The Principle A transformerless power supply (TPS) is basically just a voltage divider that takes the 115 or 220 VAC from your wall and divides it down to whatever voltage you want.

This power supply could power a 555 oscillator driving an LED. Another test used C ac =0.22µF, R1=10kO, R2=470O, R B =470O, C F =470µF, and Q1=BC549. This could be used to build a zener-transistor ...
