Company ProfileHimag Planar Ltd. has pioneered planar transformer technology from the UK since 1996.Our world-leading design engineering team have developed custom planar transformers from 35W to 50kW in a single transformer component and inductors at 350A, as well as fully developing custom power converters utilising planar magnetics technology. This design facility is an essential part of the Himag Planar organisation as most products are custom designed.

Himag Planar offers a one-stop planar transformer and inductor service; from your initial design concept right through to volume production. We aim to work alongside our customer throughout the design lifecycle, from the drawing board to the finished product. Flexibility is our ethos: we design custom magnetic components and systems to suit your specific requirements, rather than expecting you to adapt your design to accommodate a standard part.

Awards

Himag Planar Limited won the UK finals of the prestigious Shell Springboard Award for the best low carbon business idea in the UK. The award was given at a ceremony in central London to recognise the innovation of its planar transformer which dramatically increases energy efficiency in high-frequency power electronic products across the world. As an invisible but integral component of millions of electrical devices, the Planar Transformer could have a huge impact on our domestic and global carbon footprints.

The Shell Springboard program has awarded over £1.6 million to 43 UK-based small businesses and this year celebrates its fifth anniversary. Eight companies have been given no-strings awards of £40,000 each at regional events in February. Himag Planar impressed the UK final judging panel, and out of the 6 UK finalists came top to gain the further title of Shell Springboard UK winner.

The judging panel comprised Tom Delay of the Carbon Trust, Lord Oxburgh, Ben Goldsmith of Wheb Ventures and Dr Douglas Parr, Chief Scientist, Greenpeace. The judges were particularly impressed with the potential of Himag planar transformers in the solar power, electric vehicles and aerospace markets.

Dean Curran, Managing Director of Himag Planar, said: “The financial boost from the Shell Springboard award will unlock the huge market potential for our energy efficient transformers - a fundamental component of thousands of electrical devices. We can now realise our ambition of providing a technology which tackles energy inefficiency at the very core to manufacturers far and wide. Without this award we wouldn’t be able to grow as fast but, above all, it’s the accolade of being named the Shell Springboard overall UK Winner which gives us real credibility in the eyes of our customers and potential investors alike.”

Planar TransformersPlanar transformers are suited to high frequency switching applications, with a typical switching frequency of 5kHz - 500kHz. The fundamental difference between planar transformers and traditional wire-wound transformers is the planar’s use of flat copper windings, resulting in higher efficiency. Planar Windings are constructed using flat copper layers (‘lead-frames’) or printed circuit boards (PCBs) to form a laminate style winding construction, which are then sandwiched between small, light-weight planar ferrite cores. The result is a compact, high power density planar transformer that is typically around 30% of the volume and weight of its conventional wire-wound equivalent. As a result, bulky three dimensional wire-wound transformers will no longer constrain your design.

Auxiliary-Power Range

Custom Auxiliary Planar Transformers

Himag Planar manufactures a standard range of auxiliary power PCB transformers in the 10W to 55W power range. Designed specifically to offer high-voltage, low-current solutions, these planar transformers are ideal for multiple output auxiliary PSUs, in single and three phase mains powered systems:

Himag Planar also offers custom PCB auxiliary planar transformers where extreme custom capability is required. The table below is an example of a high winding count, multiple 17 output auxiliary PSU transformer for multiple axis motor drives.

Most of our business activities, including R&D and low volume manufacturing (

Custom DesignHimag Planar have been providing planar power solutions for over 13 years, offering an array of products and services to the power electronics market. We appreciate that not all designs fit into our standard product ranges and that’s why we also offer a custom design service.

We undertake projects ranging from discrete planar components to fully integrated power converters. The following are some examples of projects we have completed.

Power ConverterThe example shown below is a fully integrated planar magnetic, high voltage DC-DC Converter for a telecoms application. This is a resonant based design operating at a switching frequency of 20kHz. The converter runs from a low voltage DC Bus and is capable of delivering a high voltage output of up to 4kV @ 1Adc.

The main power transformer and output inductors are embedded within a single multilayer PCB. All other discrete components are mounted as either SMT or PTH devices on the same multilayer layer PCB:

•Rectification Diodes (SMT)

•Filter Capacitors (PTH)

•Feedback components (PTH)

•Protection Devices (PTH)

The incorporation of the magnetic components into a single PCB provides a compact solution with excellent repeatability. It also eases manufacture as there is less assembly time associated with its construction.

Planar Transformers

Integrated MagneticsWhere size and space are a real issue, integrated magnetics can provide an alternative solution to the conventional discrete component approach.Himag Planar has experience designing this type of product and this particular example, shown to the right, shows an integrated Transformer and Output Inductor assembly. This solution embeds a transformer with two inductors onto the same PCB assembly. These three components are configured for a current doubler output providing 5V @ 60Adc.

Retro FitNon-planar cores are often used when retro-fitting a planar transformer into a conventional space. Himag Planar has been asked on several occasions to design a retrofit planar transformer to replace a conventional transformer that ran too hot. A retro-fit planar transformer offers a combination of advantages, in particular the interleaving that a planar transformer construction allows, as well as a reduction of skin effect. Retro-fitting can present its own problems in terms of core selection and lead-frame/PCB design options, but has nevertheless yielded benefits. The reduction in thermal conduction area can be detrimental but as long as careful attention is paid to the interleave structure the majority of the benefits are still achievable.

High Voltage Isolation Transformers / FlexibilityHigh voltage isolation (up to 20kV) can present a challenge to any insulation system. Himag Planar overcome this by isolating one set of windings using HV Insulated wire. This allows the use of planar leadframes and PCB’s for the other winding set; greatly improving transformer size and performance. In addition Himag Planar also design transformers using multiple ferrite cores which greatly improves the effective area of the transformer. We design our own custom bobbins and fixtures to fit any combination.
