Triple Power Supply
This low-cost, multipurpose
power supply fulfils the requirements
of almost all laboratory
experiments. Nonetheless, it can
be easily fabricated by hobbyists.
A single transformer is used to
build this triple power supply. Regulator
IC LM317 generates variable power
supply of 1.25 to 20V, 1A. The dual
12V, 1A power supply is generated
by regulators 7812 and 7912. Similarly,
dual 5V, 1A power supply is generated
by regulators 7805 and 7905.
On / off switches (S2 through S4)

Roll no.65



ABSTRACT

This paper presents a method to regulate the power transferred over a wireless page link by adjusting the resonant operating frequency of the primary converter. A significant advantage of this method is that effective power regulation is maintained under variations in load, coupling and circuit parameters. This is particularly im ....etc

Programmable Power Supply (PPS)

Introduction
In laboratory and experimental work, the source of energy electric is very important.
Most products in electronics require using the current and voltage source. I propose to develop a programmable power supply as my senior project. The requirement I propose for this project is that the programmable power supply will provide the user an output voltage from one to fifteen volts at a current level up to 1 amp.
Description
For the user interface, the power supply will con ....etc

auto power supply control from 4 different sources ppt

The main objective of this project is to provide uninterrupted power supply to a load, by selecting the supply from any source out of 4 such as mains, generator, and inverter and solar automatically in the absence of any of the source. The demand for electricity is increasing every day and frequent power cuts is causing many problems in various areas like industries, hospitals and houses. An alternative arrangement for power source is a must.In this project uses four switches to demonstrat ....etc

simple power supply resumption alarm pdf

The circuit of power resumption alarm shown here is very simple, where IC1 is wired in a special kind of mode. When power supply resumes, pin 2 of IC1 is grounded through C1 and pin 3 goes high. This makes reset pin 4 to go high for about 10 seconds. When the capacitor C1 charges to two-third of the supply voltage, output of IC1 goes low, grounding the reset pin 4 and thus disabling the entire circuit.

The alarm circuit is wired around a second timer IC, IC2. Here it is used as an astable multivibrator ....etc

Abstract
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed UPS sch ....etc
