Regulated Power Supply Design Calculations

All of our calculations to determine the correct transformer will assume that the input voltage can vary from 95 to 130v and not change the output of our supply.

Regulated power supply design calculations. The following design steps cover the design of a regulated power supply with fixed output voltage or adjustable variable power supply. It also involve the calculation of different components used so the dc supple contains lesser ripples. The following design shows how simply and discretely a dual power supply could be configured using a few bjts and a few resistors. 5v power supply using 7805 voltage regulator with design by manoj shenoy electronics power supply 17 comments in most of our electronic products or projects we need a power supply for converting mains ac voltage to a regulated dc voltage.

It is a linear technology based design will go through you each design step try to present everything in simple language will carry out some design mathematics i e. With these steps you can design your regulated power supply. Online engineering calculator to quickly estimate the component values for a linear power supply. For this purpose we have to assemble a rectifier circuit on the output of a transformer.

I am going with a specific example of 5v because i think it would be best in this way to understand the whole design process. The use of a regulated linear power supply is to provide a constant output voltage over a variety of loads and also a variation of the input voltage. If a capacitor is being used in the schematic you should know why it is there and how its value is calculated. The power supply which we will design here is very basic.

The dc power supply has wide applications in the modern world.
