Active damping schemes have known a variety of applications. This paper discusses the benefits of one such scheme when applied to grid-connected voltage source converters. Particularly, it includes experimental results from applying active damping to the front-end rectifier in a double-conversion UPS. The proposed control technique improves input performance both in terms of power factor and current distortion, while ensuring stability and robustness. Actual performance has been verified in an experimental set-up under sinusoidal as well as distorted grid voltage.
