How to simulate transformers

Hello and welcome to this short blog on the simulation of transformers in Opera. Starting with the very basics of transformers, in an ideal world different windings on primary and secondary circuits produce transformed voltages and currents on the output compared to the input according to very simple calculations.

Optimal design of transformers

By Nigel Atkinson With the growing requirement to improve the design of tomorrow’s transformers, many designers and engineers are finding they need to investigate new types of transformer, with higher ratings or smaller footprint. Or quite simply, they need to improve their device’s efficiency. Engineers who have taken their designs as far as possible with hand [...] Posted in Transformer Design Software,Transformers

Webinar: Optimizing transformer design with Opera

This webinar looked at the tools that Opera has to offer allowing optimal designs of transformers, providing an understanding of how you can save experimented engineering-design man hours, increase design capacity, reduce delivery cycle and optimize the use of materials. Transformers are regarded as critical components in power systems. Market globalization has led to the necessity of being increasingly [...] Posted in Transformers

Validation of Magnetic Field Analysis with Vector Hysteresis

Introduction   The TEAM Problem 32 paper abstract is as follows[1]: “A test case for validating 2D and 3D magnetic field analysis codes, including hysteresis, is presented. For this purpose, an experimental set-up constituted by a three limbed ferromagnetic core fitted with pick-up coils has been especially designed and built. Unidirectional flux patterns and distorted […]
