DC power is input into an inverter from sources like batteries or solar panels. The inverter then converts this DC power into AC power through a process that involves switching the DC input on and off rapidly using electronic circuits. This conversion allows the generated AC power to be used for household appliances and other devices that operate on AC electricity23. Inverters are widely used in applications such as solar power systems, uninterruptible power supplies (UPS), and electric vehicles4. [pdf]
