WebPower Factor Correction (PFC) aims to improve power factor and, in turn, power quality, utilising capacitors to offset usually inductive loads, for example motors. PFC equipment achieves a decrease in the total amount of electrical demand by using a bank of capacitors to offset an inductive load (or reactors if the load is capacitive). Web9 Sep 2024 · The key to voltage conversions using an AC transformer is that power, defined as voltage-time current, is conserved. For example, 1,000 volts at 10 amps is 10,000 watts. If a transformer is used to step the voltage down to 100 volts, 100 amps will be available because 100 volts times 100 amps is 10,000 watts.
