Direct current (DC) can be converted into alternating current (AC) by using an electronic device called a power inverter. The device works by coupling it to a DC power source, such as a battery or solar panel, and then connecting an appliance or standard electrical device to the inverter to receive the AC power supply.
Electrical current pertains to the movement of charged particles through a medium called a conductor. The two primary types of electrical current are DC and AC, which mainly vary in their direction of flow. While DC is continuous and unidirectional, AC generates a wave-like or sinusoidal pattern, which enables it to reverse its directional flow multiple times. In the modern world, most power machines are designed to accept AC power. In the absence of an AC supply, it is necessary to convert DC into AC to operate these electrical devices.
Modified sine wave and pure sine wave power inverters are the two most commonly used inverters. A third type called a square wave power inverter has been phased out due to the unreliability of its power output. Modified sine wave inverters are popular for their efficiency, portability and affordability. These devices are appropriate for electrical machines that can manage voltage variations. Pure sine wave inverters, which are the priciest among power inverters, deliver the most stable output with minimal fluctuations. Medical equipment and rechargeable industrial machinery typically use these devices.
