Power Factor Correction Using Step-Up Chopper Fed to a DC Motor Drive

With the expanding interest for power from the ac line and more stringent cutoff points for power quality, power factor correction is extraordinary consideration as of late. An assortment of circuit topologies and control strategies has been created for the PFC application. While the discontinuous conduction mode (DCM) converters for example, boost and fly back converters are appropriate for low power applications. Continuous conduction mode (CCM) support converters with normal current mode, hysteresis control are absolute for some medium and high power applications. To eliminate these issues a few converter topologies utilizing proper semiconductor devices and control plans have been proposed. This examination is to find a minimal effort, small size, effective ac to dc converter to meet the UPS. In the proposed circuit, the power factor is enhanced by utilizing boost dc to dc converter. It eliminates the utilization of active switch and control circuit for PFC, which brings about higher efficiency. A Matlab/Simulink based model is introduced to get the results. At last a DC motor load is connected and simulation results are presented.
