The working of an Inverter Circuit is, it converts DC to AC, and these devices never generate any kind of power because the power is generated by the DC source. In some situations like when the DC voltage is low then we cannot use the low DC voltage in a home appliance.
An Inverter Circuit can be defined as it is a compact and rectangular shaped electrical equipment used to convert direct current (DC) voltage to alternating current (AC) voltage in common appliances. The applications of DC involves several small types of equipment like solar power systems. Direct current is used in many of the small electrical equipment such as solar power systems, power batteries, power-sources, fuel cells because these are simply produced direct current.
It supplies a stable power for household appliances, such as LED/LCD,Laptop, DVD, VCD, satellite receiver, fluorescent lamp, stereo, fan, lighting,game player, etc
