AC and DC drives are essential technologies in modern automation and control systems, offering precise control over motor speed, torque, and efficiency in a wide range of applications. AC drives (also known as variable frequency drives) are commonly used for controlling the speed of electric motors in HVAC systems, manufacturing processes, and industrial machinery, enhancing energy efficiency and reducing operational costs. DC drives, on the other hand, are prized for their high torque at low speeds and are often used in applications requiring precise speed control and rapid acceleration, such as in electric vehicles and crane operations.
