“…Unfortunately, many papers are devoted to electrothermal models of separated semiconductor devices only. For example, in the papers [23–28], [29–32], and , electrothermal models of the diode, electrothermal models of power bipolar junction transistor, and electrothermal models of power metal oxide semiconductor field effect transistor (MOSFET) are described, respectively. In previous years, some electrothermal models of integrated circuits used in switching‐mode power supplies were published, for example, in .…”
