Modeling of Current Transformers Under Saturation Conditions
Advances in Electrical and Electronic Engineering, 2006 During a short circuit the input signal of the relay can be distort by the magnetic core saturation of the current transformer. It is useful to verify the behavior of CT by a mathematical model. The paper describes one phase and three phase models and it

Current Control of Saturated Synchronous Motors [PDF]
2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018 Synchronous reluctance motors (SyRMs) with or without permanent magnets (PMs) have highly nonlinear saturation characteristics. The effects of the magnetic saturation can be included in the current controller by changing its state variable from the stator current to the stator flux linkage using the known saturation characteristics.

A Novel Shielded IGBT (SIGBT) With Integrated Diodes
IEEE Journal of the Electron Devices Society, 2020 A novel 3.3 kV Shielded Insulated Gate Bipolar Transistor (SIGBT) is proposed in this paper. Unlike the partly shielded N-injector of the diode-clamped TIGBT, which is the carrier store layer, the SIGBT features a diode-clamped P-layer to completely ...
