Working Of Inverter

In this article we learn about the main working of inverter. we will know about what is working of inverter.

An inverter is used to produce an uninterrupted 220V or 110V AC (depending on the line voltage of a particular country) supply to the device connected as the load at the output socket. The inverter gives constant AC voltage at its output socket when the AC mains power supply is not available.

The working of inverter can be considered in the following conditions.

When the AC mains supply is available, the AC mains sensor senses it and the supply goes to the relay and battery charging sections of the inverter. AC main sensor activates a relay and this relay will directly pass the AC mains supply to the output socket. The load will be driven by the line voltage in this situation.

Also the line voltage is given to the battery charging section where the line voltage is converted to a DC section where the line voltages is converted to a DC voltage (12 V DC or 24 V DC usually).  Then regulated and battery is charged, using it.

There are special circuits for sensing the battery voltage and when the battery is fully charged this charging is stopped. In some inverters, there will be a trickle charging circuit which keeps the battery constantly at full charge.

When the AC mains power supply is not available, an oscillator circuit inside the inverter produces a 50HZ MOS drive signal. This MOS drive signal will amplify by the driver section and sent to the output section. MOSFET,S  or transistors are used for the switching operations. These MOSFETs are used for the switching operations. These MOSFET s or transistors are connected to the primary winding of the inverter transformer.

When these switching devices receive the MOS drive signal from the inverter circuit, they start switching between ON and OFF states at a rate of 50HZ. This switching action of the MOSFETs or transistors causes a 50HZ current to the primary of the inverter transformer.  This result in a 220V AC or 110V AC (depending on the winding ratio of the inverter transformer) at the secondary or the inverter transformer. This secondary voltage is made available at the output socket of the inverter transformer. This secondary voltage is made available at the output socket of the inverter by a changeover relay.

Hence it is the working of inverter if you will find any incorrect in above article please comment below in comment box.
