This thesis focuses on the study of a hybrid power factor correction for ac-dc
converter. It uses a hybrid control method where analog and digital controller integrates
to control the input voltage and current waveforms to achieve a unity power factor
correction. This converter operates in average current mode control.
The digital controller is realized with an 8-bit (G6053) microcontroller configured
as PI compensator to compensate the output voltage to its desired output value. This can
improve output voltage regulation against line and load variations. This hybrid converter
operates in CCM mode and a switching frequency of 100 kHz to achieve low harmonic
distortion, low ripple output voltage and high efficiency. Moreover, this converter circuit
is verified through Matlab/Simulink behavioral simulation and actual implementation of a
hybrid PFC converter.
Finally, experimental verification results show the improvement is effective. It
gives a higher power factor closes to unity with high efficiency. The converter efficiency
is higher than required energy-efficiency imposed by Energy Star. Then, the THD is
approximately 9.6% and a ripple output voltage around 0.93%.
