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

Abstract:
The number of industry applications in which induction motors are fed by static frequency inverters is growing fast and, although much has already been done within this field, there is still a lot to be studied/understood regarding such applications. The advance of variable speed drives systems engineering increasingly leads to the need of specific technical guidance provision by electrical machines and drives manufacturers, In this paper we have studied and developed a simulink model with PWM inverter and find out the variou ....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

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

Hi
This is mechatronis project , where Most commercially available low-cost DC-AC converters (Frequency control / inverters) give a square wave of 50Hz output. This is sufficient for a number of devices, especially for devices operating with a transformer. The professional training that a sinusoidal output signal is generated, can also be used to control motors, but is much more expensive. The intention is to build this type of control with the microcontroller. The intention is that through a screen and some buttons speed and run speed is adj ....etc
