Inductors & Chokes

Exxelia SVM reactors improve system performance by eliminating unwanted harmonics in equipment with non-linear loads.

Exxelia SVM designs inductors and chokes to block high-frequency ripple currents. Examples include filter inductors (5 mH, 15 A rms at 40 kHz; 10 mH, 10 A; dimensions specified). They also provide LCL filter inductors using rectangular Litz wire rated for high current (e.g., 100 µH, 360 A continuous, 510 A peak, 50 Hz–3.5 kHz).

Exxelia SVM develops fully custom magnetics, offering in-house tooling, MATLAB/FEMM modelling, special core designs, Litz wire constructions up to 350 A, and complete solutions from prototype to packaging.

Exxelia SVM develops SMPS transformers in multiple topologies (flyback, push–pull, forward converter, gate drive, pulse), supporting up to 500 kHz. They cover various core geometries (EE, EFD, ETD, PQ, RM, ER, Pot, Toroid…) with conductors such as enameled copper, triple-insulated wires, Litz, and twisted wires.

Exxelia SVM provides Hall-effect current transformers for high-speed AC and DC measurement up to 50 kHz.

Exxelia SVM designs high-frequency transformers operating up to 100 kHz and 500 kW. Custom units are also available, such as dry-type transformers (30 kVA at ~30 kHz, up to 50 kV DC) and high-voltage models (80 kVA, 20 kHz, ±25 kV outputs).

Exxelia SVM offers linear isolation transformers with high efficiency that comply with IEC and UL safety standards, e.g., a 3 kVA isolation transformer at 230 V / 50 Hz.
