BRIDGELESS POWER FACTOR CORRECTION THESIS

The control circuit was implemented using dsPIC30F A Caltech Library Service. There are multiple solutions in which line current is sinusoidal. The increasing growth in the use of electronic equipment in recent years has resulted in a greater need to ensure that the line current harmonic content of any equipment connected to the ac mains is limited to meet regulatory standards. The simulation results are shown that voltage output is able to be control in steady state condition for single phase AC to DC power factor correction interleaved boost converter by using this methodology.

This class of converters presents an opportunity for accurate comparison with related conventional topologies, which is included to show the advantages of the new approach. The bridgeless converter is designed for obtaining the low conduction losses and requirement of low size of heat sink for the switches. There are multiple solutions in which line current is sinusoidal. The increasing growth in the use of electronic equipment in recent years has Fuzzy control has been used for switching pulse generation in the converter. This requirement is usually satisfied by incorporating some form of Power Factor Correction PFC circuits to shape the input phase currents, so that they are sinusoidal in nature and are in phase with the input phase voltages. A simulation and practical results were presented.
