Switch mode power supplies (SMPSs) are used in a range of applications as an efficient and effective source of power. This is in major part of their efficiency. For anybody still working on a desktop, look for the fan...
Useful for electronics hobbyists, this linear workbench/ desktop power supply converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable three-pin voltage regulator chip LM317T (IC1) is...
in this video, the author has made a circuit which takes 12VDC as an input and generates 220VDC as an output. This SMPS circuit can be used to power up your Laptop charger inside a car or from any...
Different blocks in the DVD player system require different DC supply voltages to power them. For example, logic circuitry may require 5V, DSP, MCU and memory chips may require 3.3V, motors in DVD/CD drives mechanisms may need 12V and...
Most electronics enthusiasts require DC power supplies to operate various devices and accessories. The most popular and common supply is a 12V DC supply that can be easily derived from the household AC supply with transformation, rectification, filtering and...
It is always good to reuse and repurpose old electronics. This project shows you how to build an adapter that can turn an old computer power supply into a bench power supply for your workshop. Any ATX power supply...
