3 COMPANY PROFILE Himag Planar possess over two decades of experience in the field of planar transformers with a long history in inverter technology and PCB design. Himag Planar has become the global market leader in the development of planar transformer technology, design and manufacture. We have as a group to date manufactured million s of planar transformers, including thousands of custom planar transformer designs. As part of a wider group we are a truly global company with manufacturing & engineering design facilities in Israel, USA and Asia as well as the UK. We manufacture from one off bespoke quick turnaround prototypes through to volume production both in the UK and overseas. Our structure and resources cater for all of our customer requirements. In the UK we are housed in our own 7000 square foot facility which we are currently updating ensuring we keep pace with increasing production as Planar technology becomes the standard for high frequency electronics. 5 Planar s Advantages PLANAR TECHNOLOGY Planar s are suited to high frequency switching applications, with a typical switching frequency of 20kHz 5MHz. The fundamental difference between planar transformers and traditional wire-wound transformers is the use of flat copper conductors, resulting in higher efficiency due to the ability to interleave windings and to design the conductor for skin effect. 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 cores. The result is a compact, high power density planar transformer that is typically smaller, lighter, and more efficient than its conventional wire-wound equivalent. High Efficiency (>99%) Low profile Lightweight (5g per W) Low Leakage Inductance Repeatability (Controlled Parasitics) Customised Terminations High Efficiency Multiple Multiple Winding Options Dimensional Accuracy kv, typical Reduced EMI

17 CUSTOM DESIGN 2 CUSTOM DESIGN 150kW Planar Medical Planar Himag Planar specialises in high power planar transformers. The great challenge is thermal performance of these high power parts. One option Himag employs to overcome this is by using multiple units hence increasing the thermal conduction area. This example is a single transformer assembly using two planar transformers that are connected in series & parallel to achieve 150kW. Specification: Total output power - 150kW (2 x 75kW) High Efficiency >99% Leakage <0.01% Frequency - 20kHz Mechanical dimensions: Length - 9 mm, Width - 75mm, Height mm Weight kg A Planar with a continuous power rating of 6.5kW with short periods that require 12kW. The transformer is designed with 2 pairs of E6 ferrite cores and is mounted on a baseplate with an aluminium heatsink clamp. The transformer has a turn s ratio of 11:2+2:17. This transformer is in the power supply for a medical CTI scanner and it is housed in the rotating part of the equipment that exerts pressures of 6G. The terminals for the primary winding and two separate secondary windings are made using Litz wires that are connected prior to potting of the part. The potting is not only important to the thermal capabilities of the transformer but also plays an important role in the structural integrity of the part. Power Converter This is a fully integrated planar magnetic, high voltage DCDC 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 1A DC. 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) High Voltage High voltage isolation can present a challenge to any insulation system. Himag Planar overcame this (in this case 20kV) by a hybrid approach with the primary windings using a HV Insulated wire and the secondary planar leadframes. This solution improves the transformer size and performance. The use of multiple cores allows for higher power ratings due to the increased effective area of the ferrite.

18 THERMAL HANDLING / COOLING In operation s and Inductors generate significant heat, and this heat has to be dealt with. It is much more efficient to cool these parts by conduction rather than convection (radiation). The low profile flat nature of the Planar provides a relatively large core surface area ideal for conduction cooling. The flat planar windings of the component can also utilise conduction cooling by the placing aluminium blocks between the windings and the same cooling surface of the core. The following cooling methods are used by Himag in the majority of designs:- The Water Cooled plate is a very efficient heatsink method as the temperature of the cooling surface can be maintained at a constant temperature by the use of a coolant. Single Sided The magnetic component is mounted direct to a cold plate or heatsink providing a single cooling surface for both the core and windings. Two Sided As well as being mounted on a heatsink or cold plate the top surface can also be cooled by a clamping bar providing a thermal path from the top surface of the component to the heatsink or cold plate via the mounting parts. Three Sided Achieved by a formed clamp bracket providing a thermal path from the top and sides of the part down to the cold plate or heatsink. Finned Heatsinks & Forced Air: provide a conduction and radiation method for single, double, and three sided cooling with the same construction methods as the water cooled plate. The fins of the heatsink increase the surface area of the cooling medium, and further improvement is achieved by applying forced air over the component, with the fins significantly improving the thermal radiation process. The use of thermal grease, high thermal conductive tapes, and adhesives can be employed to further enhance the thermal performance of the component in all of the above cooling methods. Potting the component with a high thermally conductive resin material can further improve thermal performance. The ingress of the potting material into the component assuring all surfaces of all materials have a thermal path to the cooling surface. The additional mass of the component as a result of the potting material will also improve the thermal process by absorption of the heat.
