Design challenge - do you need EMI chokes or filters for high currents in restricted space?
There are a lot of standard components for EMI suppression like common mode chokes, differential chokes, or filters for currents up to 20 A. Common-mode currents (unbalanced currents plus disturbances to attenuate) seldom exceed 100 mA. However, even in this range, the requirements to manage EMI can be unique depending on the application, with a high number of design parameters to be considered, ie. surrounding equipment, space, environmental impacts. This means customised solutions are often required to meet the application's specific needs.
In addition, when exceeding 100 A nominal and/or 5 A common mode current, component design becomes exponentially more challenging because of size: high current wire needs space and a lower number of wire turns to achieve proper attenuation, and hence a certain inductance level, meaning the design needs to include enough core cross-section and enough turns around the core, which normally results in huge chokes or filters. However, by utilising different core materials and shapes, wire cross-sections, and winding designs we can find an optimum design that meets your operational parameters.
