What Is An Inverter?

The job of the inverter is to convert the DC voltage to the AC voltage. The DC voltage comes as input and the AC is the output. The former is less than the latter.  Usually the AC output is equal to the routine grid supply that varies from region to region. Usually it is from 120 volts to 240 volts. The inverter serves multiple purposes. It can be used as a supporting device to the solar power and can also be installed to overcome the power problem by working as a power back up device. In the latter situation the inverters are connected with the batteries that get easily charged and then supply the power when there is a break down. 

For large working areas that require enough power from time to time inverters are connected to a power supply unit or the UPS. The inverters exist in a number of forms. Usually they are classified into different types according to the size, shape and the working capacity. All these   types serve the purpose of operating the electronics and the electronic devices of different ties. They have different switching technology thus the circuits are also different due to these varying switching technologies.

The inverters   are classified according to the output, source, load, technique, and the output level. Under these classifying factors the inverters can be further sub divided as following:

  1. According to the output the inverters have three sub types. The least used of the three is the square wave inverter. In this case the wave for is in square shape. The simple applications like the universal motor use these kinds of inverters. The perfect inverter in this category is the sine   wave inverter that is the part of domestic systems. The third in this category is known as the modified sine wave. It has complex construction but the performance is great.
  2. According to the source the inverters are of two types. Voltage source inverter gets the voltage as   the source. It is   commonly known as    Their response time is great and they are extremely reliable. The current source inverter is great for the medium voltage installations.
  3. According to the load the inverters are categorized into single phase and triple phase inverters. The former works in case of the single phase supply and is further classified into half and full bridge inverters. The triple phase inverters work for the industrial zones. Their two popular models are 180 degree   mode and the 120 mode.
  4. The inverter types according to control technique are Single Pulse Width modulation (single PWM), Multiple Pulse Width Modulation (MPWM), Sinusoidal Pulse Width Modulation (SPWM), and the Modified Sinusoidal Pulse Width Modulation (MSPWM). The technique means that how many signals are being used by the inverter. Check this website to find out more details.
