Explanation: VFDs are commonly used to control the speed of electric motors, which are inductive loads. Inductive loads, such as motors, require a certain amount of current to establish a magnetic field before they can start running, and VFDs can provide this by smoothly ramping up the frequency of the power supplied to the motor.
