WebPower factor can be defined as the ratio of real power (Active power) to apparent power. It can also be defined as the absolute value of the cosine of the phase shift between the voltage and current in an AC circuit. It is denoted by the Greek alphabet λ (Lambda). Power factor (λ) = Active power/Apparent power. = VI.COS φ/ VI. WebThe power factor correction (PFC) control is proposed to reduce harmonic components and improve transmission efﬁ-ciency by achieving unity power factor. Under this condition, the input voltage and current are regulated to be in-phase, so the system can be viewed as a pure resistance and all power generated by source are totally transferred to ...
