Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer steps down the voltage applied to it. For instance, a step down transformer is needed to use a 110v product in a country with a 220v supply.

Step down transformers convert electrical voltage from one level or phase configuration usually down to a lower level. They can include features for electrical isolation, power distribution, and control and instrumentation applications. Step down tra ....etc

Introduction

An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
Static inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are co ....etc

3. BLOCK DIAGRAM OF 12V DC BOOST REGULATOR
The figure shows the simple block diagram of the 12V dc boost regulator. Each block can be separately assembled and checked. The functioning of each block is discussed below.
Figure 3.1 Block Diagram of 12V DC Boost Regulator
3.1 DC SUPPLY
It is the external dc input applied to the circuit. The boost regulator circuit corrects variations in the supply voltage. Additional current is drawn by the boost circuit to get the required output voltage.

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

lm317 12v battery charger

Automatic Battery Charger Circuit Design:

This automatic battery charger circuit design mainly involves two sections power supply section and load comparison section.

The main supply voltage 230V, 50Hz is connected to the primary winding of the center tapped transformer to step down the voltage to 15-0-15V.

The output of the transformer is connected to the Diodes D1, D2. Here diodes D1, D2 are used to convert low AC voltage to pulsating DC voltage. This process is also called as rectification. The pulsating DC vol ....etc
