This report presents the design implementations and control of a single-phase ac-dc converter. The implemented rectifier is in the form of a bi-directional full-bridge boost rectifier comprising of four transistor switches. They are featured to operate at high switching frequencies and are controlled by applying the sinusoidal pulse width modulation technique. For the rectifier system, an adaptive controller is included to maintain the dc output voltage regulation as well as to attain near-unity power factor. This implies that the input current would be in phase with the source voltage from the grid supply. The schematic of the converter and controller are designed and integrated together for conducting the tests. The experimental results of the simulation are provided to show the capability of the controller, by evaluating its feedback performance with respect to the converter to ensure for a regulated output voltage in the system.
