In this paper an analysis of two planar transformers designed for high-current switching applications is presented. Typical converter application is represented by fuel and electrolyser cell converters. The transformer designs are based on E+I and ER+I planar cores while the analysis focuses on winding resistance and leakage inductances which represent the main concerns related to low-voltage high-current...
This paper presents an analytical model to evaluate the inter-turn short-circuit current in a Fault Tolerant Permanent Magnet Synchronous Machine (FT-PMSM) for different winding configurations. By evaluating slot-leakage and air-gap fluxes, the inductance of both healthy and faulty parts of the phase winding, as well as the mutual inductance between them, can be determined for any position and number...
The paper deals with calculation of start-up characteristics of a Boucherot type squirrel cage winding of an induction machine. The characteristics themselves are calculated in two possible ways - considering and neglecting saturation of machine's steel. The results of both types of calculations are compared and checked through measured start-up test.
This paper uses multi-conductor transmission line (MTL) to model transformer windings. According to the symmetry of windings, a 2D equivalent finite element model can be set up under ANSYS environment. On the basis, finite element method (FEM) is used to calculate the distributed parameters in transformer windings. In the process of calculation, the skin effect is focused on. The frequency-dependent...
In this paper, a high frequency physical phase variable model of electric machines is presented. The proposed model is composed of a low frequency phase variable model and a high frequency winding branch connected in parallel. The high frequency winding branch is used to include the distributed effects appearing at high frequency operation while the low frequency phase variable model captures the...
