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

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

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

Lazer Power Supply

Lazer works in high voltage supply.How can we make high voltage out of 220/110 V AC.Here gives the circuit.You can use this to make high voltage supply.But prevention should be taken to avoid shoking hazards.

The circuit takes 115 V supply and gives to step up transformer. Three diodes and three capacitors are used to eliminate the ripples of AC.

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
