90 kW frequency converter driven synchronous reluctance machine losses are determined simultaneously with the input-output powers and with the calorimetric method. Uncertainty of both measurement methods is analyzed and discussed. Calorimetric measurement system that is capable to determine the losses of the motor frame size up to 315 is introduced.
The precise measurement of the power dissipated by a semiconductor device operating in fast dynamic conditions is an important issue in power conversion circuits to evaluate their overall efficiency. Measurement errors can be introduced in particular by the probes or by instruments that are transparent to high dv/dt and di/dt rates. For this reason, the use of bulky and expensive set-up's is often...
