Abstract

The drive to improve power electronic system efficiencies makes the accurate and repeatable determination of power losses ever more important. As operating frequencies, harmonic content and efficiency increase, electrical methods of
measuring loss become more uncertain since they are affected by phase-errors and electromagnetic interference among other factors. Alternative calorimetric methods allow system losses, which manifest as heat, to be measured directly with a high degree of accuracy. However, calorimeter facilities tend to be
costly bespoke measurement systems which is a barrier to their widespread use. In this paper, an extension to the closed double-jacket type calorimeter topology is presented which offers comparatively low-cost, simplified construction and improved flexibility with the aim of promoting a more widespread use of calorimetry within the power electronics community.
