On-State Voltage Drop Analytical Model for 4H-SiC Trench IGBTs

open access: yesCrystals, 2022
In this paper, a model for the forward voltage drop in a 4H-SiC trench IGBT is developed. The analytical model is based on the 4H-SiC trench MOSFET voltage model and the hole-carrier concentration profile in the N-drift region for a conventional 4H-SiC ...

A Converter-Level on-State Voltage Measurement Method for Power Semiconductor Devices

open access: yesIEEE Transactions on Power Electronics, 2021
This letter proposes a converter-level method for measuring the on-state voltages of all power semiconductors in a single-phase inverter by using a single circuit only. The proposed circuit distinguishes itself by connecting to the middle-point of each phase-leg, instead of the two power-terminals of individual devices as conventional methods do.
