An inverter is electronic equipment that is responsible for the conversion of direct current (DC) into alternating current (AC). In the majority of the cases, the input DC voltage is very low to that of an output AC. The latter depends upon the grid supply voltage containing 120 volts or sometimes 240 volts.The overall frequency, power handling capacity, input and output voltage is based upon the architecture of a particular device or circuits. The equipment does not generate power as it is transmitted through the DC source.

Power inverter is a blend of mechanical reactions and electronic circuits. A uniform inverter does not leverage moving parts during the conversion process. They are best suited for various electrical power applications that contain the presence of a very high voltage and currents.

Those circuits which carry out tasks for electronic signals possessing a very low voltage and current are known by the name oscillators. On the other hand, circuits that execute reverse function i.e. conversion of AC to DC is termed as a rectifier.

An inverter is designed as a stand-alone device for applications including solar power or it is leveraged as a back-up power supply that is powered by batteries. Today, there are diverse ranges of inverters that are based upon the architecture of a switching waveform with different circuit configurations, pros, and cons.

Features of an Inverter

A standard circuit features an oscillator, control circuit, switching devices, drive circuit for power equipment as well as a transformer. The transformation of DC to AC is attained through the conversion of energy preserved in the DC source like batteries or straight from a rectifier output to alternating voltage. The process is carried out by utilizing several switching equipment which is frequently activated and turned off and enhancing it with the help of a transformer.

There are quite a few configurations that do not leverage a transformer. DC input voltage is turned on and off using power devices and power transistors and the pulses are supplied directly to the side of a transformer. The variations in voltage kindle an alternating voltage in the secondary winding.

Three major inverter output stages are push-pull bearing a center tap transformer, push-pull half-bridge, and push-pull full bridge. Push-pull containing a center tap is a popular one owing to its simplicity and optimal outcome, but a major concern concerning it is that it has a minimum efficiency and uses a heavy transformer.

How are the inverters classified?

An inverter is categorized based on output waveforms bearing three types of waveforms namely square wave, pure sine wave, and modified sine wave. The first one is simple and cost-effective but it has a very low power quality when compared to the other two but the remaining waveforms provide the best power quality.
