Observer based temperature control for reduced thermal cycling in power electronic cooling (2013)
Journal Article
Wang, X., Castellazzi, A., & Zanchetta, P. (in press). Observer based temperature control for reduced thermal cycling in power electronic cooling. Applied Thermal Engineering, 64(1-2), https://doi.org/10.1016/j.applthermaleng.2013.12.001

This paper presents an advanced dynamic cooling strategy for multi-layer structured power electronic modules. A observer based feedback controller is proposed to reduce a power device or module's thermal cycle amplitude during operation, with the aim...
