MAGNETICS: Transforming the future of power electronics

Himag continues to design and manufacture its 2kW-50kW range of planar transformers in the UK, and has recently expanded its facility in China to include this power range for larger volume customers, in addition to the <2kW products it has been supplying out of China since 2008. Himag provides a full-cycle service, bespoke-design through to volume manufacture, of high-frequency magnetics (planar and conventional). Planar transformers can be used as a direct replacement for conventional wire-wound transformers in high-frequency power electronics applications, with typical switching frequencies of 20kHz – 1MHz. Typically a planar transformer is >99% efficient, and around 30% of the volume and weight of its conventional wire-wound equivalent. Planar transformers are important to the future of any electronic product requiring a high frequency switch mode power supply. The main advantages of planar transformers over their conventional counterparts are as follows: • Improved Efficiency • Low Profile • Low Weight • Low Leakage Inductance • Highly Efficient Cooling • High Repeatability • Multiple Topologies • Dimensional Accuracy • Multiple Windings Options After extensive R&D work in 2013, Himag has now taken its first orders for its new range of high-power planar transformers (50kW+): Sectors such as traction, powering modern-day requirements such as in-seat charging points on trains, are adopting Himag's new planar transformers that offer up to 120kW in a single-component in a size smaller than a ream of paper. The image shows one bespoke-designed example of a 100kW planar transformer, with an integrated water-cooled coldplate, offering an efficiency of >98% with leakage inductance of <0.01%, weighing <10kg in dimensions of 360mm x 160mm x 70mm. Company and product info Himag is a global leader of planar transformer and inductor technology, offering a wide range of innovative custom-design magnetics (conventional and planar) providing very high-efficiency (typ 99%+), in a lightweight compact form factor, for all high-frequency electronics. Himag's Engineering team have developed single-component planar transformers from 5W to 120kW, up to 20kV, including integrated transformer/inductors and SMPS with integrated magnetics. Product range includes wire-wound transformers and chokes through to full power supplies and off-shore low-cost sub-assembly service. Product range In addition to its expertise in planar transformers and inductors, Himag also designs and manufactures a large range of wire-wound magnetics products: including choke coils, line filters, and lamination transformers. Himag also provides an off-shore low-cost sub-assembly service: including power supplies and adapters, PCB assembly, injection moulding, metal casing and more… Standards and certifications ISO 9001:2008.
