  • Abstract This thesis presents a reactive power and capacitor voltage controls method for the Vienna converters in three-phase three-wire system. The control method can realize rectification and low current total harmonic distortion (THD), which can make converter operate with power factor correction (PFC)mode, PF leading mode, PF lagging mode and achieve two loads output power balance or unbalance. This control method can enhance converter ability and make it more flexible to application. Furthermore, the reactive power and capacitor voltage balance controls operation limit had been analyzed. In addition, the converter operation principle had been derived and either reactive power or unbalance load controls method were analyzed. Besides, the relation and limitations between both control is investigated. This method used the carrier-based pulse width modulation and zero-sequence injection method to achieve the requirements. Finally, a three-phase Vienna converters was built with DSP TMS320F28335. All the key concepts and ideas developed in this thesis is implemented in this hardware system and verified by the experimental results.
