The word ‘inverter’ in the context of power-electronics denotes a class of power conversion (or power conditioning) circuits that operates from a dc voltage source or a dc current source and converts it into ac voltage or current. The ‘inverter’ does reverse of what ac-to-dc ‘converter’ does (refer to ac to dc converters).
A typical inverter looks something like the above. It has some red and black DC terminals on the back end and on the front end we find some AC electrical outlets. That’s because there are two types of electricity, AC and DC. An inverter is used to convert DC or direct current into AC alternating current.
Most inverters rely on resistors, capacitors, transistors, and other circuit devices for converting DC Voltage to AC Voltage. In alternating current, the current changes direction and flows forward and backward. The current whose direction changes periodically is called an alternating current (AC). It has non-zero frequency.
The electrical circuits that transform Direct current (DC) input into Alternating current (AC) output are known as DC-to-AC Converters or Inverters. They are used in power electronic applications where the power input pure 12V, 24V, 48V DC voltage that requires power conversion for an AC output with a certain frequency.
Inverters are complex devices, but they are able to convert DC-to-AC for general power supply use. Inverters allow us to tap into the simplicity of DC systems and utilize equipment designed to work in a conventional AC environment. The most commonly used technique in inverters is called Pulse Width Modulation (PWM).
An inverter that converts a direct current into an alternating current is called a DC-AC inverter. However, the term “inverter” generally refers to the equipment that combines an AC-DC converter (that changes an alternating current into a direct current) and a DC-AC inverter so as to be able to generate arbitrary frequencies and voltages.
