The function of an inverter is to convert direct current (DC) into alternating current (AC) . Inverters are used in a variety of applications, including:
-
Home appliances: Inverters are used in air conditioners, home theaters, electric grinding wheels, power tools, sewing machines, DVDs, VCDs, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, and lighting.
-
Car appliances: Car inverters are powered by car batteries or cigarette lighters and are used to power electrical appliances in cars.
-
Industrial equipment: Inverters are used in a wide range of industrial equipment such as printing presses, fans, pumps, conveyor belts, food processing equipment, and construction machinery.
-
Solar energy systems: Inverters are used in solar energy systems to convert DC electricity from solar panels into AC electricity that can be used in homes and businesses.
Inverters can also control the speed and torque of electric motors, which are found in most devices we use to do work such as small electronics, transportation, and office appliances. Inverters are used to match the motors speed to the required process to avoid wasting energy, boosting productivity, and saving energy. The output voltage of an inverter can be a clean, repeating sine wave that can be injected into the power grid.
Different types of inverters are available, including pure sine wave inverters and modified sine wave inverters. Pure sine wave inverters produce a waveform that matches the destination power source, while modified sine wave inverters use square wave output. Modified sine wave inverters are suitable for most applications but can make the motor hot while running and are not suitable for high power requirement appliances like refrigerators, air conditioning, home water pumping motor, and similar devices.
