Power factor is an important performance parameter of electric network. This parameter becomes very significant when power electronics circuits are used in different application. Active power factor is one of the method used to improve the power factor but it is very costly. Valley fill circuit is a passive power factor used with power electronic circuit particularly with artificial light application. The objective of this paper is to analyze valley fill circuit with simulation and hardware. Simulation is done by using PSIM simulation software and a prototype hardware is made for comparison.
