Abstract :
Analyzing and measuring power losses of power electronics and motor system are of great importance. This paper compares several methods for power loss calculation and measurement. A general scheme for modeling losses of power semiconductors is given. As for the harmonic losses of converter-fed motors, an effective FEM process is described. The constraint of conventional calorimeter is discussed and a simplified calorimetric method is introduced.
