Harmonic Current Reduction Techniques for Computer Systems
Overview With today's increased use of modern electronics has come a corresponding concern about harmonic currents and their effects on the power system. Most modern electronic equipment contains static power converters which generate harmonic currents. Harmonic currents flow in the power system as reactive power (VAR), adding to the apparent power demand (VA). In addition to the increased apparent power demand of nonlinear loads, the harmonic currents cause additional heating and stresses in the power system components due to their higher frequencies. In some circumstances, the nonlinear load's harmonic currents can excite harmonic resonances, cause undesirable system interactions, or cause misoperation of other equipment.
