EXXELIA at PCIM 2019
Exxelia will exhibit custom design power transformers and inductors as well as capacitors at PCIM in Nuremberg, Germany, from May 7th to 9th 2019 in booth #136.
Notable at Exxelia’s booth #136 will be custom design power transformers & inductors such as:
FERRITE TRANSFORMER 100kVA-20kHz
This transformer combines high power up to 100kVA, at very high frequency 20kHz, while still providing a weak leakage inductance. Used in an isolated DC/DC converter, its unique morphology made of U and I 126 magnetic circuit improves considerably thermal dissipation while the litz wire winding reduces high frequency losses. Characterized by a primary circuit at 540V / 350Arms and a secondary winding at 270A, this transformer ensures high performance and maximum leakage current reduction.
3 PHASE INDUCTOR 3x5,5mH-9kHz
Used in a high performance converter, this three-phase common mode choke withstands the highest current up to 580A thanks to the use of copper bar for winding while ensuring a minimal inductance of 1,4mH and filtering the far-reaching noise. This deisgn is characterized by its extreme reliability thanks to its magnetic circuit made of 24 nanocrystalline tores, chosen to guarantee a stable inductance value across the temperature range -30°C to +140°C.
Larger Batches of High Q-Factor Dielectric Resonators
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. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
Exxelia at Space Tech Expo – Booth #5009
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 power and high frequency ceramics with the new C48X dielectric Range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10–4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. Magnetic components based on adaptive CCM technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The CCM technology adapts to most every need, even the harshest environments, including VIGON® resistance. The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC.
