TL;DR: This article tackles the practical difficulties associated with capacitor core-temperature estimation using the capacitance and demonstrates a successful implementation strategy for applying this method in power converters to estimate core temperature online.

TL;DR: The condition monitoring system proposed in this paper is based on the online estimation of the capacitor's equivalent series resistance using the switching frequency components of the dc-link capacitor voltage and current, and is adapted for the condition monitoring of capacitors in industrial power converters.

TL;DR: In this article, an experimental investigation of active dc, PWM power cycling and passive thermal cycling approaches on 1.2-kV 50-A fast trench insulated gate bipolar junction transistor (IGBT) devices is presented.

TL;DR: The fault detection circuit is based on monitoring the collector-emitter voltage using external collector capacitor, and the protection circuits are based on softly turning off the gate voltage using a current diode, which reduces power dissipation, temperature rise and prevents damage of the drive system.

TL;DR: In this paper , a 13-level boost inverter topology has been analyzed and the test results are presented and discussed in terms of open-circuit fault, short-circuits fault, power loss, and thermal analysis.
