Variable Frequency Drive Working Principle

Variable Frequency Drive Operating Principle Whilst there are a number of variations in variable frequency drive design they all offer the same basic functionality which is to convert the incoming electrical supply of fixed frequency and voltage into a variable frequency and variable voltage that is output to the motor with a corresponding change in the motor speed and torque.
