Abstract: Efficient and stable power electronic devices are critical components in order to increase energy efficiency which at the eventual will reduce carbon emission. As one of intermediary power electronic devices, power converter is now becoming a subject for rapid development to support the idea of emission reduction. This project is to develop microcontroller-based three-phase inverter and rectifier that can be functioning as the interface between battery, three-phase load, and utility grid. SPWM for inverter, PWM for rectifier, and control modules are realised using an Infineon microcontroller. The type of control used in the three-phase inverter is feedforward while proportional-derivative (PD) controller is employed in the rectifier side. To add controllability feature in rectifier, DC-DC buck converter with one IGBT switch is cascaded with rectifier. The IGBT switch is controlled using PWM emitted from microcontroller that is amplified by a driver. Both inverter and rectifier experimental results were showing similarity as seen in the simulation results. The inverter successfully generated three-phase waveform from a DC input, meanwhile rectifier also showed a good operation by having a DC output when AC waveform was injected at the input. Adding controller module improved the inverter performance which was indicated by a moderate disturbance rejection and improvement in wind-up avoidance was observed after adding PD controller in rectifier module. In this report, a little highlight of background knowledge and previous final year projects are reviewed as well as presenting the details of design, simulation, experiment, results, and conclusion. In addition, recommendations for future project are also given in this report.
