Abstract
A detailed model of Adjustable Speed Drive (ASD) is discussed, which yield a general rule for active damping in a small DC link based drive. A desired value of input LC resonance damping coefficient can be achieved by changing gain parameters. The modified state space matrix due to active damping terms is also presented. The performance of the active damping is evaluated based on experimental results. A simple model is presented which can be used to measure the damping factor provided by the system parameters only.
