The problem of electromagnetic compatibility in active magnetic bearing systems is studied, and the aspect of this specific problem is illustrated. The main concern of this work is electromagnetic inference caused by power amplifiers. The modeling methodology of power amplifiers is studied, and a nonideal simulation model with essential distributed parameters considered is obtained. Simulation work is carried out to reveal the mechanisms of the electromagnetic inference signal generation. The results validate the modeling and indicate potential measures to reduce electromagnetic inference of power amplifiers.
