Inverters are electrical devices that are used to convert direct current (DC) to an alternating current (AC).In the previous post we discussed the designing of an inverter circuit. In this post, we will focus on the working principle of an inverter.
What Does An Inverter Do When Mains Is Available?
Most of us think that an inverter is only operational when there are power cuts. On the contrary, an inverter is a device that is working continuously. How? For example, there are no power cuts and the mains power supply is available. In such case, an inverter uses this supply to charge its batteries, which can later be used in case of power cuts. When the batteries are completely charged, the inverter no more gives supply to the batteries, and runs your appliances on a bypass mode. When not in use, batteries tend to discharge slowly. Again inverter switches its role to charge them back.
How Does An Inverter Help in Cases of Power Cuts?
It is not the job of an inverter, but a battery to store electricity. The main purpose of an inverter is to convert the AC power from power stations into DC power, and store it in the batteries. Why can’t you store this power in the available AC form? The answer to this question is that batteries get charged only by DC power, and not by AC. Now to run different appliances, the DC power stored in the batteries is required to be converted to AC power. This task is performed by inverters.
