Abstract: In this paper, the nonlinear compact thermal model of power semiconductor devices based on the Cauer network is proposed. The analytical description of the model and the method of the model parameter estimation are presented. The accuracy and usefulness of the model is verified experimentally for the selected metal-oxide-semiconductor (MOS) power transistor at its various cooling conditions.

TL;DR: In this paper, the nonisothermal characteristics of switchmode voltage regulators (VRs) consisting of the boost converter with discrete semiconductor devices and a monolithic current-mode pulsewidth modulation controller are modeled.
Abstract: The paper concerns modeling the nonisothermal characteristics of switch-mode voltage regulators (VRs) consisting of the boost converter with discrete semiconductor devices and a monolithic current-mode pulsewidth modulation controller. New electrothermal hybrid models of a p-n diode and a power metal oxide semiconductor transistor, as well as the electrothermal model of the monolithic UC3842 controller dedicated for SPICE analysis of switch-mode VRs are presented and described in detail. The results of simulations verified experimentally are given as well.

TL;DR: A new method for fast estimation of the characteristics of single-inductance dc-dc converters at the steady state with self-heating taken into account is proposed, based on the special memoryless convolution algorithm.
Abstract: In this paper, a new method for fast estimation of the characteristics of single-inductance dc-dc converters at the steady state with self-heating taken into account is proposed. This method is based on the special memoryless convolution algorithm. The method is described in detail. The theoretical considerations are illustrated with simulation results of buck and boost converters.

TL;DR: In this article, a synthesis of different electrical methods used to estimate the temperature of power semiconductor devices is presented, including voltage under low current levels, threshold voltage, voltage under high current level, gate-emitter voltage, saturation current, and switching times.
Abstract: This paper proposes a synthesis of different electrical methods used to estimate the temperature of power semiconductor devices. The following measurement methods are introduced: the voltage under low current levels, the threshold voltage, the voltage under high current levels, the gate-emitter voltage, the saturation current, and the switching times. All these methods are then compared in terms of sensitivity, linearity, accuracy, genericity, calibration needs, and possibility of characterizing the thermal impedance or the temperature during the operation of the converter. The measurement of thermo-sensitive parameters of wide bandgap semiconductors is also discussed.
