Objectif
- Accurate behavioural models, accounting for geometry and frequency dependent effects are obtained for the SMPS magnetic components. Layers position, sensitivity to track and isolation dimensions, etc., will be calculated with the new MEMT tool.
- Improvement of magnetic component performance, because the capability to obtain an accurate model before building the magnetic component and the physical insight by means of the Finite Element Analysis allows component optimisation.
- Improvement of SMPS, because performance of SMPS is highly dependent on magnetic components. Efficiency, stress, size, thermal management, etc, are more accurately calculated since accurate models are available.
- Improvement of design process: allows performance of electrical simulations and to check whether results are as expected before building magnetic component and SMPS.
- Development time reduction: design will not be iterative. Iterations will be done by computer, but not in the construction of the magnetic components.
- Cost reduction: due to the development time reduction and manufacturing cost of low profile PCB transformers, that is lower than hand made transformers when leakage inductance reduction is a must, as in this case.
Performance and design process of Switched Mode Power Supplies (SMPS) are improved by means of the improvement of the design, modelling and manufacturing process of the power magnetic components. The influence of magnetic components in high frequency DC/DC converters is critical. Furthermore, the performance of HF magnetic components is very dependent on winging strategy and geometry effects, which are not properly calculated and predicted today. The Magnetic Element Modelling Tool (MEMT), based on Finite Element Analysis calculations, is used to generate accurate frequency dependent behavioural models, useful to guarantee adequate performance and save time in the design and development process of the whole SMPS.
