Designing the power conversion section
Magnetic cores for inductors and transformers
When designing inductive components like transformers and inductors, choosing the right material is the first challenge. There are over a dozen material classes, with a huge variety of sub-classes, brands, grades, and types. A developer has to match their application's requirements with the parameters of each material and give consideration to the cost implications.
A developer needs to match their application’s requirements with the parameters of each material and give consideration to the cost implications. Our portfolio covers a wide range of specialist soft magnetic materials including EDGE, XFlux, Kool Mu Max from Magnetics Inc., Iron Powder from Micrometals as focus materials for inductors; Amorphous, Nanocrystalline from our Acal BFi kOr product line, and ferrites from Ferroxcube for transformers. We can help you select, source, customise, stock, and integrate soft magnetic cores.

Common mode chokes for EMI filters - cores and components
When designing modern and often complex integrated systems, engineers must consider the possibility of electromagnetic interference (EMI), which affects the performance of the system and can lead to a failure to meet regulatory standards.
To contain conducted emissions the usual solution is to add a filter at the input stage of your system and common mode chokes (CMC) are the basic component of the filter. This allows the target signal to pass unaffected, whilst filtering out undesired signals.
The expertise within our in-house Magnetic Products Technology Centre enables us to select the right material and design the best core to build your common mode choke. We offer nanocrystalline (see inductors and transformers section) and ferrite cores.
We can also offer a list of ready-made common mode chokes from our suppliers Magnetec and Laird.

Designing custom magnetics
When designing a power conversion module for a charging application, magnetic components are vital and need to be designed using the competencies of soft magnetic cores, wires, insulation, plastics, and heat dissipation.
With a well structured team of technical support specialists in Europe, we are able to design with you custom solutions for magnetic cores or components within power conversion applications.
Our Magnetics Products Technology Centre can develop a solution to achieve your goals, whether your need is simple or complex.
- Consultancy on soft magnetic cores. We not only select the best technology for you, but we can also design the best-suited core for your application
- Starting from your basic specifications, we design the inductive component and produce rapid prototypes to test the concept
- Manufacturing of the components
- Setup a dedicated logistic strategy to secure your supply chain
Typical products we can develop are common mode chokes, PFC chokes, transformers, EMI filters, and 50Hz safety and monitoring components (current transformers and RCDs).
Thermally conductive products
High current power conversion produces heat that must be dissipated safely to avoid overheating causing EMI issues or even premature failure of electronics inside the application.
We offer market-leading thermal interface materials from MTC, that combine high thermal conductivity and low viscosity whilst maintaining insulating properties.

Temperature sensors
Temperature sensors are used across a range of applications in electric vehicles, such as temperature monitoring of the charging cable, charging pile and Battery Management System (BMS).
These applications call for sensors that are suited to harsh environments, accurate measurement, fast detection of a change in temperature, enhanced reliability and quality.
With Shibaura’s high-quality glass encapsulated thermistors, which provide superior performance, quality and reliability, our temperature sensors are able to withstand high voltages and temperatures up to 1000°C.

Protecting users from your EV charging system

Current sensitivity components
Electric vehicle charging systems require the capability to measure current in order to detect uncontrolled situations which may cause permanent system failures.
Our Magnetic Products Technology Centre offers cores for different types of RCDs (Residual Current Devices). Electric vehicle charging requires all-current sensitivity, detecting pure DC currents and any currents with higher frequencies above 50Hz. We are able to tune properties (hysteresis loop shape, permeability, and temperature behaviour) of nanocrystalline cores ( Acal BFi kOr 118 and 120).
- Optimum combination of high linearity and highest permeability
- Negative temperature coefficient µ(T) (as standard)
- Plastic case or epoxy coated for example as RCCB core: Bdyn/Bsin > 0.85 at µmax = 150.000 and >0.80 at µmax = 200.000
Transformers
When power management ratings increase, you may need 50/60Hz transformers to connect your charger system to the grid. We offer a specialist range of transformers designed for smoothing in rectifiers, reducing short-circuit currents, AC filtering, and high-frequency switching.
These transformers are manufactured according to a customer’s exact requirements. Noratel is able to design and produce anything from small single-phase toroidal to large tri-phase EI transformers with heavy current coils for larger electric vehicle charging installations, with everything developed in close co-operation with the customer.
|
EMI shielding
For safety and reliability, it is critical that charging stations meet the industry’s full requirements. Electric vehicle charging stations equipped with advanced capabilities such as power electronics and cloud-based communications fall under the class of devices that require EMC testing and certification.
To help protect your device we offer a broad range of components and materials for the shielding of EMI, such as:
- Fabric-over-foam (FoF) gaskets, electrically conductive foams, elastomers, tapes, and contact springs
- Shielded windows, metal honeycomb vent panels, and fan vents
- Metal contact springs and pads
- FOF made of aluminium foils or copper-nickel fabric
