General purpose inverters are widely used power electronic devices in the industrial control field. They convert the input AC power into DC power with adjustable frequency and voltage, which is then supplied to the motor to achieve precise and continuous control of the speed of AC motors. General purpose inverters feature a wide speed control range, precise control, significant energy-saving effects, excellent starting performance, and various control modes, such as V/f control, vector control, and direct torque control. They are suitable for applications such as fans, pumps, conveyors, elevators, and many other devices, making them an essential component in industrial automation systems.
