Inverter working principle

Inverter working principle: An inverter is an electronic device that changes direct current to alternating current. We should remember that inverter never produces any power, the power is provided by the DC source.

In most of the cases, the input DC voltage is usually lower. We can’t use lower voltage in the home appliance. This is why we need to use inverter when we use solar power panel.

There are, broadly speaking, two kinds of inverters: modified square wave inverters and sine wave inverters. The modified square wave inverters is actually a square wave where the voltage is periodically 0

During the conversion process, the voltage is increased. In Ohm’s law, we know that an increased voltage also leads to a decrease in current. So the overall current is decreased when the DC signal is converted into an AC

Depend on the working principle, there are two types of inverters:

  1. Stand alone inverters
  2. Grid tie inverters.

Stand Alone Inverters

It is the basic type of inverters which along with the inversion of DC to AC and also produce increase the amplitude of the voltage hence produce a change in the frequency.

This kind of inverter output usually in sine wave but some cases the output gets distorted due to several reasons and appears in the form of a modified sine wave or a square wave.

Grid Tie Inverters

As the name refers that the output AC power is supplied to a grid-type network. For example, A large-scale supply unit. Then the power is distributed through the unit. For this reason, it has a complex construction and internal circuitry because they have to synchronize with the grid network.

These are the two basic type of inverter. Inverters can be enormous and heavy—particularly on the off chance that they have worked in battery packs so they can work in an independent manner. They additionally produce bunches of warmth, which is the reason they have extensive warmth sinks (metal balances) and regularly cooling fans also.
