Custom designs improved with new magnetic simulation tools

According to Martin Carlzon, R&D Manager at ETAL: “Our investment allows us to achieve designs that match customers’ expectations much more closely, and achieve them more quickly at lower cost. Whether the design objective is to deliver a level of performance within a budget, achieve a desired level of efficiency or to push the envelope and create something exceptional, our new tools will move us towards the goal more quickly. When we produce a prototype we do so with confidence that its performance will match the electronic model closely.”

The ETAL electromagnetic field simulation capability allows their design team to create a very accurate model of a magnetic component within the CAD package. They can try the impact of different materials, wires and air gaps, tuning the design to get as close as possible to the parameters required by the customer.

The simulation software uses the finite element method to simulate low-frequency electromagnetic fields in industrial components including 2D magnetic transient, AC electromagnetic, magnetostatic, electrostatic, DC conduction and electric transient solvers. It will accurately solve for field parameters including capacitance, inductance, resistance and impedance.

ETAL now also offers its customers the benefit of a full 3D CAD tool suite, giving it the capability to create production level drawings that the customer can readily import into their own suite. They can move forward with the mechanical and electrical design of their system without a physical sample of the finished component.

ETAL manufactures and sells in-house developed high-performance magnetic components such as transformers and inductors, which are used in AC/DC converters, DC/DC converters and signal applications.

Target markets include the telecom, power technology, automotive, industrial and defence industries. The majority of components are custom-designed for specific applications, but ETAL also offers a range of standard components. It also develops and manufactures the Anaview range of high-quality Class D amplifiers for the global audio industry.
