Components of an Inverter
There are mainly five components of an inverter. They are as follows:
Microcontroller
A microcontroller is also known as Digital Signal Processor. This is the core of the inverter that is responsible for managing the switching of electric conversion. It also regulates the voltage so that the frequency remains stable. Microcontroller also detects faults or issues if present. This processor also ensures that maximum output and minimum energy loss.
Bipolar Junction Transistors
A transistor is a semiconductor device whose task is to amplify the signals. These are used to basically switch quickly from one type to another type. Here two kinds of transistors PNP or NPN are used.
Filter
This is used to filter the frequencies based on the requirements. It will allow to pass high frequencies if high frequencies are required and vice versa. It also smooths waves so as to produce perfect AC output.
MOSFETs
MOSFETs or Metal-Oxide-Semiconductor-Field-Effect-Transistor are responsible for high switching. They are used for switching between high frequencies so that the inverter can correctly chop off the Direct currents and convert them to AC.
Heat Sink and Cooling System
Since in inverter there is switching between high frequencies and converting low powered DC to high powered AC, a large amount of heat is dissipated. So to avoid over heating appropriate heat sinks are required. Also cooling systems are required so as to maintain the temperature of the inverter.
Introduction to Inverters
Current is defined as the flow of electrons. It is denoted by I and the SI unit of current is Ampere. There are mainly two types of currents: Alternating Current (AC) and Direct Current (DC). In general AC is used to travel over long distances and users require DC.
So, there are many devices that are used to convert incoming Alternating current to Direct Current. Examples include SMPS, Power Adapters, Chargers etc. But we also need devices that convert Direct Current to Alternating Current.
