Power factor correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor that is less than one. Power factor correction may be applied either by an electrical power transmission utility to improve the stability and efficiency of the transmission network or correction may be installed by individual electrical customers to reduce the costs charged to them by their electricity supplier. In order to improve transmission efficiency, power factor correction research has become a hot topic. Many control methods for the power factor correction...

In this research work, a novel approach using a switching resistor is proposed for reducing the distortion. Investigations are carried out to analyze the effect of load on the IGBT based power system developed using the concept of switching resistor. Harmonic distortions in the input and output of the system are calculated. Input and output voltages waveforms are recorded for all combinations by using signal recording software having duration of 1s with sampling rate of 16,000sa/s. Computer algorithm is designed to calculate the total harmonic distortion (THD) in the system. Reduction in the...
