Web1 de jun. de 2004 · If PF is corrected to 1.0, then reactive power=0 and apparent power=SQRT (95 2 +0 2 )=95. This demonstrates an actual reduction of energy consumption and peak demand of 5% (100kVA-95kVA=5kVA). Ideal power factor is unity (1.00), which means that the load is using 100% of the power to perform actual work. WebNon power-factor-corrected SMPSs also cause harmonic distortion. This can be prevented if a (properly earthed) EMI/RFI filter is connected between the input terminals and the bridge rectifier. Acoustic noise: Faint, usually inaudible mains hum, usually due to vibration of windings in the transformer or magnetostriction. dhop new england trade
