A thermal analysis has been performed for a package design pertinent to power electronics. The objective has been the derivation of straightforward expressions that relate the materials used and their physical dimensions to the power input and the junction temperature. This has been done for both steady-state operating conditions and for pulses. The role of phase change materials (PCMs) in suppressing temperature elevations during pulses is also addressed.
