Abstract

A digital technique based on real-time error compensation is proposed for an automatic measurement station for high efficiency variable speed drives testing. This technique allows to achieve high accuracy on power measurements by a real-time compensation of the errors of the transducers, An experimental verification of the proposed methodology is carried out by measurements performed on an actual electrical drive, and compared to the results obtained by high precision commercial instrumentation
