Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

The solutions provided by Exxelia's Smart Magnetic project are revolutionizing the field of electrical converters by offering unparalleled performance in terms of power density.

Smart Magnetics Exxelia

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.

 

Functional advantages for increased reliability:

The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke.

The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy),

Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.

 

Rationalization of the value chain for optimized production costs:

The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.

 

Contribution to a more environmentally friendly industry:

By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.

 

Various applications:

The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.

MIL Spec 39006, Now available in LEVEL R

Exxelia, global manufacturer of complex passive components and subsystems for harsh environments, is expanding its line of MIL-PRF-39006/22 & MIL-PRF-39006/25 tantalum capacitors, with the support of the reliability level R. MIL-PRF-39006 tantalum capacitors equivalent to CLR79 and CLR81 series: this is the new range of gelled tantalum capacitors meeting the standards required by the US Department of Defense in the manufacturing of components (compatibility & reliability).   Exxelia now offers reliability level R, in addition to level M and P for voltage ranges from 6 V to 125 V with capacitance values ranging from 1.7 µF to 1 200 µF. Available in all package sizes (T1 to T4), these fully sealed products are designed to operate at temperatures ranging from -55°C to +125°C and withstand the harshest environmental conditions. Performance highlights over solid tantalum capacitors include higher energy density, higher ripple currents, lower ESR and lower DC leakage current. Engineers with complex design requirements looking for a product that can be easily integrated into projects such as power supplies & converters or filtering units for the aerospace and defense industries will be pleased.  MIL 39006/22 & MIL 39006/25 Level R are now available for order with a lead time of 14 weeks.   "The introduction of these new ranges builds on our decades of experience in supplying high reliability capacitors to the military market and demonstrates Exxelia's ability to meet the most demanding specifications in terms of product development" says Jerome Tabourel, Exxelia's vice president of sales and marketing. "We are proud to be one of the few MIL qualified tantalum capacitor manufacturers, and our flexibility and advantageous lead times will bring new supply opportunities."   TECHNICAL CHARACTERISTICS Capacitance from 1.7 μF to 1,200 μF Voltage from 6 V to 125 V Operating temperature -55°C to +125°C Very good shock and vibration resistance (option H available)   Download the complete datasheet

Ultra low ESR, high RF power and high self-resonant frequency The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking. 100% invar tuning screws with self-locking system   Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed. High Q Factor Dielectric Resonators in large batches Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication.
