How Inverter Works
First, let’s understand what is an Inverter?
Inverters are electrical devices that are used to convert direct current (DC) to an alternating current (AC). At our homes, we get AC power supply, and due to of its properties it cannot be stored, hence we store DC power in a battery which comes with an inverter.
Still confused on inverter working?
We will divide this answer in parts for a better understanding.
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.
What Does an Inverter Do When there is no Power Cut?
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.
What Does an Inverter Do When there is a Power Cut?
When there are power cuts, an inverter switches itself from mains mode to the backup mode. In this mode, the inverter uses the charge stored in the batteries to run different appliances. While the inverter switches its mode, the appliances that are running stop for few seconds. After a gap of few seconds, they restart on the back up mode. Now inverter provides power only to those appliances which have been connected to inverter supply and rest of the appliances till they get supply from mainline.
Automation in an Inverter
Inverter consists of a number of different circuits, which are responsible to sense and handle several situations while an inverter is in a stand by or running mode. These sections are referred to as automation sections, and they respond to conditions such as:.
• Over charge
• Low Battery.
• It provides pure sine wave output for your sensitive appliances at homes and offices.
• Over heat
Based on the situation, this section switches the battery in a suitable mode either switch OFF mode or charging mode. LEDs and alarms are provided in this section, which notify the operator about the different conditions and situations. In advanced inverters, these conditions are displayed with the help of LCD screens.
