- Abstract:
- An experimental study about uncertainty in measurements of conducted emissions generated by a variable speed drive in the frequency band 150 kHz to 30 MHz due to variations in the power voltage, driving conditions and amplitude of torque applied to an electrical load is presented. A global index based on the weighted distance between measurements and standard limits is introduced to help to single out which factors have the largest influence on emissions. Results show that frequency of motor and torque applied to it can in fact cause relevant changes. One interesting takeaway is that when testing power drive systems for compliance to conducted emission standards, more specifications should be given about operating conditions in order to keep uncertainty related to test conditions at acceptable levels.
