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...

Power Electronics have proved itself as an encompassing field for power generation and 1IlaI1ag4:me Traditionally conversion of ac to de vo~es has been dominated by phase controlled or diode rectifiers. The ideal character of the input current draWnby these rectifiers creates number of problems like increase in .. power, high input current harmonics and low input power factor, lower rectifier e...
