Built as a modern reimplementation of the original Electronic Transformer Toolkit, PyETK provides a backend-driven architecture that transforms structured transformer definitions into ready-to-solve finite element models. The toolkit automates geometry creation, winding generation, material assignment, matrix connections, and Eddy Current simulation setup, including optional frequency sweep analyses. Support is provided for planar and wound transformer topologies using rectangular or circular conductors, with built-in libraries of commonly used magnetic core geometries and materials. PyETK also models frequency-dependent permeability and Steinmetz core-loss characteristics, enabling accurate evaluation of high-frequency magnetic devices. By leveraging PyAEDT, PyETK enables use through Python scripting, automated workflows, REST services, and graphical user interfaces, reducing the effort and expertise required to perform high-fidelity electromagnetic simulation. ## Key Benefits Automates transformer and inductor model creation, reducing manual setup effort and engineering time. Accelerates design iteration by enabling rapid evaluation of multiple design alternatives. Improves modelling consistency through standardized, repeatable workflows. Supports both GUI-based and Python-driven operation for engineers with varying levels of simulation expertise. Enables scalable batch processing and design automation for optimization studies. Provides accurate high-frequency electromagnetic analysis using Ansys Maxwell solvers. Integrates easily into existing engineering workflows through APIs, structured input data, and automation frameworks. Reduces the expertise required to create high-fidelity transformer simulation models while improving productivity and reproducibility. ## Use Cases Generate ready-to-simulate transformer and inductor models directly from analytical design calculations. Integrate electromagnetic validation into in-house design, sizing, and optimization workflows. Perform rapid evaluation of alternative core, winding, and material configurations. Automate design-space exploration and parametric studies using Python-based workflows. Create frequency-dependent transformer models for downstream circuit and system-level simulation. Enable batch generation and simulation of multiple transformer variants. Support third-party software integration through structured data exchange and API access. Evaluate high-frequency effects, including leakage fields, proximity effects, and core losses, using Maxwell finite element analysis. ## Images ![PyETK Backend Screenshot](/sites/default/files/2026-09/BackEnd.png "PyETK Backend Screenshot") PyETK Backend Screenshot ![PyETK FrontEnd Screenshot](/sites/default/files/2026-09/FrontEnd.png "PyETK FrontEnd Screenshot") PyETK FrontEnd Screenshot ![PyETK Results](/sites/default/files/2026-09/Results.png "PyETK Results") PyETK Results ## Latest version PyETK Electronic Transformer Toolkit 0.4.1 Supported Ansys versions: 2025 R2, 2026 R1 [Download](/app/ansys-inc/pyetk-electronic-transformer-toolkit/0-4-1/download-app) Go to top Publisher![Publisher logo](/sites/default/files/%5Bdate%3Acustom%3AY%5D-%5Bdate%3Acustom%3Am%5D/ansys-part-of-synopsys-logos-full-color-rgb.jpg) Ansys Inc Support information Southpointe 2600 Ansys Drive, Cannonsburg, PA USA 724-746-3304
