An inverter is an electronic device that converts direct current (DC) power—such as from a battery—into alternating current (AC), typically 220V at 50Hz, either as a sine wave or square wave. This conversion allows devices that require AC power to function even when only DC power is available. Inverters are commonly used in various applications where portable or alternative power sources are needed.
They are widely used in home appliances such as air conditioners, home theaters, electric grinders, power tools, sewing machines, DVD players, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, and lighting systems. These devices often rely on standard AC power, but inverters make it possible to use them with DC sources like batteries, especially in mobile or off-grid environments.
In simple terms, an inverter takes low-voltage DC power—usually 12V, 24V, or 48V—and converts it into 220V AC power. This is the opposite of what most electronics do, which usually convert AC to DC for operation. The term "inverter" comes from this reverse process. With the rise of mobile lifestyles—whether for work, communication, or leisure—there's a growing need for flexible power solutions. People now expect to have access to both DC and AC power sources wherever they go. Inverters provide a practical solution by enabling the use of standard AC devices in situations where only DC power is available, making them essential in modern living.
