Transformer Power Supply And Filter Experiment

Now clear a doubt.

Transformer power supply and filter experiment.

The circuit is shown in figure 1. A power supply has been assembled for you and is available from the laboratory tas. Supplies normally consist of a transformer a rectifier bank and a filter. In other words for a transformer there is no direct electrical connection between the two coil windings thereby giving it the name also of an isolation transformer generally the primary winding of a transformer is connected to the input voltage supply and converts or transforms the electrical power into a magnetic field.

This large current may damage the diode and at the same time it causes greater heating of the power transformer resulting in decreased efficiency. Terminal strip with at least three terminals. Create a 1 2 ratio step up transformer by connecting the two primary windings in series and the two secondary windings in series. Electrical current into d c.

Filters and power supplies introduction a power supply takes alternating current or a c. It is intended to be used to make electromagnets because many turns of wire may be wrapped in a relatively small diameter coil. L c filters power supply filters. Stepping down voltage first step is is scale down the voltage by a step down transformer a step down transformer converts the 220 ac voltage to the lower ac voltage.

Through the reclamation power resources office in denver and via the manuals and standards development program. Firstly 220v ac is converted into 12v ac by using simple step down 220v 12v transformer. Low voltage ac power supply magnet wire is small gauge wire insulated with a thin enamel coating. T 1000 transformer has four windings.

Power supply block diagram. Power from your electric utility con edison and converts the a c. Maximum people thinks that a transformer give dc output voltage because we don t get shock by touching its output wire but this is totally wrong. The objective of this project is to convert 220v ac supply in to 12v and 12v dc supply that is why it is named dual power supply as we get positive and negative 12v power supply at the same time.

This transformer will also be used in the next part of the experiment so leave the connections intact when the present part is finished. The authors gratefully acknowledge the assistance of all who. Power supplies have several com ponets which are at first understood separatly and then they are joined together. Simple shunt capacitor filter reduces the ripple voltage but increases the current through the diode.

Household wall socket power plug and cord. Transformers have been used at powerplants since the inception of alternating current generation a century ago. Any gauge of wire will work but 28 gauge is recommended so as to make a coil with as many turns as. There are three step.
