The proposed active three-phase rectifier circuit utilizing a Flying Converter Cell (FCC) based on the concept of third harmonic injection allows the extension of a passive three-phase diode bridge rectifier to a low-harmonic input stage (THDi <; 5%) for applications where dc-link voltage control is not required. In this work the design and experimental verification of a 10kW laboratory prototype using the proposed concept is addressed. Based on the analysis of the rectifier system a control concept is developed which is implemented in a digital signal processor. It is shown that the proposed rectifier system shows several degrees of freedom which can be used for system optimization. Several implementation details are discussed and experimental results taken from the constructed 10kW laboratory prototype demonstrate the good performance of the proposed rectifier system and verify the proper operation of the developed control concepts.
