Abstract:
Power factor is an important performance parameter of a system. If the power
factor of a system is low, it draws more current from the supply. So improving power
factor is very much essential for better and economic performance of a system. This
seminar report introduce a new power factor correction circuit which overcomes all
the drawbacks of conventional power factor correction approaches. This proposed
circuit will provide output voltage range of 257V, with input power factor 0.81 and
input current THD of 40 % . Here bridgeless buck rectifier output is given as input
to the boost converter for maximising the output voltage level. Simulation has been
carried out to study the performance of the proposed topology in MATLAB R2010a
/SIMULINK environment.
