A carrier-based modulation (CBM) method is proposed for indirect matrix converters (IMC) to reduce common-mode voltage (CMV). The proposed method is developed by utilizing two triangle carriers with opposite phase, and the phase with the minimum absolute output voltage uses the different carrier. The range of zero-sequence signals is given, and the selection of zero-sequence signals and the arrangement...
Large-capacity high-voltage inverter satisfies demand of energy saving and emission reduction. This paper presents a new 25MVA/10kV high power motor driving system based on IEGT power modules. The paper introduces the system configuration, and separately describes the design of power modules, the main control system, and motor control algorithm in details. Finally, the experiment results are shown...
