In order to achieve fast and efficient hybrid powertrains, it is necessary to develop new electronic devices such as inverters and DC-DC converters. However, one of the biggest challenges facing inverter applications is that installation space is very limited. Therefore, Vacuumschmelze has introduced a compact filter choke series.
Germany's Vacuumschmelze company has developed a series of new automotive-certified ultra-microcrystalline chokes. According to the company, this product has high attenuation and permeability characteristics, which can meet increasingly strict safety regulations and EMC (Electromagnetic Compatibility) vehicle network requirements.
The choke coil adopts powder-shell core structure, the magnetic leakage inductance is extremely low, and it has excellent electromagnetic compatibility performance. At temperatures up to 150 ° C, peaks of 300 A can be reached. The installation space of the inverter is limited, and the mechanical requirements of the components are very high. The tolerance is only ± 0.3mm, but the automatic production can ensure stable quality and cost level.
Future automotive applications, such as electric air-conditioning compressors, electric roll stabilizers, and electric turbochargers, are likely to further reduce carbon dioxide emissions. Because these functions are called in the car only when needed, that is, on-demand power. Vitroperm nanocrystalline core current compensation chokes have the advantages of wide temperature range, small size, and uniform temperature.
