Types Of Residential Inverters I

Inverters are used in many different applications and each of them have their own advantages and disadvantages. Let us first analyze the advantages of an invertor. An inverter is an electronic circuit or device that transforms direct electrical energy to alternating current by means of a phase conversion. The resulting AC voltage obtained varies according to the type of device used. Inverters can be single phase or multiple phase.


For instance, an invertor can be used to convert a direct power supply (DC) signal to a lower voltage (AC) signal. It is useful in multiplexer applications, such as switching a single circuit, such as a motor, from primary to alternate current (AC). For the latter, a multiplexer is also necessary, but the speed of the switching process is determined by the power rating of the individual circuit, which can be a function of the input load of the motor.

Inverters are commonly used in communications systems. They are used to convert AC power to DC current, in order to enable devices such as computers to operate. AC to DC is also used for the purpose of charging motor vehicles. These inverters are also used in home appliances such as refrigerators and ovens. Some other applications include marine, military, and industrial applications. Thus, there are great opportunities for using these devices.

Inverters are based on certain principles, and one of the most important among these is the loop design. A simple DC source is connected between the terminals of the inverter. This DC source will be turned into alternating current (AC). On the other hand, this DC source will be linked with a coil that is placed at the center of the inverter. In the process, both the AC and DC energy will be transformed into alternating energy.

There are many different types of Inverters that can be used for the above-mentioned applications. The two most popular types are the conductors driven and the pulse drives. The drives use an external device, such as a magnetic switch or a spring, to change the DC into AC voltage. Due to the action of the spring, the gate voltage will be smaller than the actual AC voltage. To control the pulse frequency of the drive, these inverters have variable pulse width control.

Another type of Inverters is the battery operated inverters. These devices run on the principle of the battery life. Since the battery voltage is low, the inverters consume less energy than the DC input voltage of the utility grid. The batteries come into use only when the DC input voltage of the utility grid is not able to support the heavy load of the inverters. The battery powered inverters are therefore very efficient and reliable.
