The main goal of this final year project was to attain a PF close to unity for the diode rectifier-fed high voltage gain boost rectifier by implementing a PFC controller. At the same time, the secondary goal is to achieve a fast response for the output of the rectifier. The diode rectifier-fed high voltage gain boost converter was able to function with the four controllers constructed. The four controllers implemented are as follow: (a) non-adaptive sliding mode controller, (b) adaptive sliding mode controller, (c) non-adaptive current mode controller and lastly (d) adaptive current mode controller. All four controllers were able to achieve a close to unity PF despite not having a sinusoidal ac current waveform. Overall, the adaptive sliding mode has the best performance, followed by non-adaptive sliding mode and then the current mode ones.
