Transformers are widely used in electronics to modify voltage before electrical energy is transmitted. Alternating current in one coil generates a varying magnetic field that induces electromotive force, allowing power to be transferred from one coil to another via a magnetic field without the use of a metallic connection.

Depending on the circuit's requirements, designing these electronics systems is the art of maximizing or minimizing induction. In systems where maximum inductance is required, such as a shared iron core within an electric transformer, computational electromagnetics can confirm good coil proximity and sizing. Alternatively, identifying stray flux leakage is desirable when the inductance is undesirable, such as between a circuit coil and metal framing used in a housing. Current is required to drive the coil, but you don't want electromagnetic effects to be inducted within the framing and, as a result, generate unwanted heat or reduce system efficiency.

We are particularly skilled at modelling ideal and toroidal transformers. The results of these simulations can be used to optimise electric transformer performance and to identify areas in a circuit where electromagnetic screenage/shielding may be required. For an ideal electric transformer, this could entail looking at ways to improve inductance by incorporating a shared ferrite core into the circuit.

Our functionality really shines when it comes to modelling true coil geometries as well as coils approximated as cylinders. True coil geometry is represented by the realistic distribution of magnetic effects between and around coil turns, with air modelled within and around the wiring. It generates magnetic fields that are intended to remain contained within the core of toroidal transformers, requiring less electromagnetic screenage and making them ideal for concentrated environments.

We can assess the magnetic flux inside toroidal transformers and identify areas where leakage may occur. Discovery AIM's advanced electromagnetic adaptive meshing capabilities, which automatically optimize meshing in areas of high electromagnetic effect, support these findings. Mesh generation is automated and physics-aware, with customizable tool options for skin depth resolution, core loss, and eddy effect computation.
