SAE J2953/2This SAE Recommended Practice SAE J2953/2 establishes the test procedures to ensure the interoperability of Plug-In Vehicles (PEV) and Electric Vehicle Supply Equipment (EVSE) for multiple suppliers.
Sampling RateDefines the number of samples per unit of time (usually seconds) taken from a continuous signal to make a discrete signal.
Second Harmonic DistortionRatio of second-order harmonic to the input signal (carrier). Often measured as dBc.
Seebeck CoefficientThe voltage built up when a small temperature gradient is applied to a material, and when the material has come to a steady state where the current density is zero everywhere. If the temperature difference ΔT between the two ends of a material is small, then the Seebeck coefficient of a(...)
SemiconductorA material whose electrical conductivity is poor at low temperatures but is improved by minute additions of certain substances or by the application of heat, light, or voltage. In its pure form it has electrical conductivity that is usually between that of a metal (such as copper) and that of(...)
Serial CommunicationThe process of sending data one bit at a time, sequentially, over a communication channel or computer bus.
Shielded RoomA room made free from EMI by applying shielding to the floor, walls, and ceiling, and by suppressing interference entering through the power lines. Typical construction shields from 70 dB to 140 dB from 10 kHz to 10 GHz.
Shielding EffectivenessMeasured using plane waves in the far field (relatively far from the radiating antenna).
Signal IntegrityA set of measures of the quality of an electrical signal.
SIA set of measures of the quality of an electrical signal.
Skin Effectthe tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor
Standards BodiesAny organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of some relatively wide base of affected adopters.
SusceptibilityA measure of how easily a dielectric polarizes in response to an external electric field.
Switch Mode Power SupplyAn electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
