提高电力电子系统效率的驱动力使得准确和可重复地确定功率损耗变得更加重要。随着工作频率、谐波含量和效率的增加，测量损耗的电气方法变得更加不确定，因为它们受到相位误差和电磁干扰等因素的影响。替代的量热方法允许以高精度直接测量表现为热量的系统损失。然而，热量计设施往往是昂贵的定制测量系统，这是其广泛使用的障碍。在本文中，扩展到封闭的双护套型热量计拓扑结构，提供了相对较低的成本，简化的结构和提高的灵活性，其目的是促进更广泛的使用热量在电力电子社区。
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.
