Abstract in another language
A simple liquid-filled container above the power semiconductor chip increases the thermal capacitance in a certain time range at higher power levels, thereby minimizing the thermal impedance by about 25%. Measurements on a hardware prototype with a periodic load profile at different time constants show that the temperature swing can be reduced, significantly improving lifetime. A simple, one-dimensional network model is presented to reproduce this non-linear, temperature-dependent behavior of the thermal impedance for simulations.
