Power Factor Correction (PFC) Handbook ON Semiconductor. ment and distortion factor as it pertains to power factor. Irms(1) is the currentвЂ™s fundamental component and Irms is the currentвЂ™s RMS value. Therefore, the purpose of the power factor correction circuit is to minimize the input current distortion and make the current in phase with the voltage. When the power factor is not equal to 1, the current wave-form does not follow the voltage, Methods of Power Factor Improvement Capacitors: Improving power factor means reducing the phase difference between voltage and current. Since the majority of loads are of inductive nature, they require some amount of reactive power for them to function..

3 POWER FACTOR IMPROVEMENT USING ACTIVE POWERFACTOR. Power factor play an important role in AC circuits and power dissipation depends on this factor. For instant, we know that; Power in a Three Phase AC Circuit = P = в€љ3 V x I CosР¤ And Current in a Three Phase AC Circuits = I = P / (3 V x CosР¤) Now, In case of Low Power Factor, Current will be power factor correction (pfc) of ac-dc system using boost-converter a thesis submitted in partial fulfillment of the requirements for the degree of.

By definition, the power factor (PF) of an AC source is defined as the ratio of the real power, in watts, flowing into the load to the apparent power in the circuit, which is the product of current and voltage. Average current control Boost Converter for the improvement of power factor and total harmonic distortion has been used in this work. The boost converter is a highly
