AC POWER DELIVERY FOR REDUCED CORROSION
This abstract first appeared for US patent application 20250112488 titled 'AC POWER DELIVERY FOR REDUCED CORROSION
Original Abstract Submitted
electric fields that can cause corrosion of contacts can be compensated for by embodiments of the present invention. for example, voltage waveforms at the contacts can be made to have a zero volt average, and therefore have a zero net electric field. galvanic voltages generated by dissimilar metals used by a contact and a housing can generate an electric field, and currents motivated by the galvanic electric field can be blocked by capacitively coupling the contacts to their corresponding circuits.
