Abstract |
As there are more applications of T-type inverter, the concern of the inverter reliability has been increasing. This thesis investigates the operation modes of three-level T-type inverter circuit, proposed a new method to detect fault phase .The proposed method can locate fault switch by detecting the average value of phase current and the situation of unbalance voltage of capacitors. Carrier-based pulse width modulation is applying to achieve the tolerance control, and making the modulation scheme more easier to implement. A neutral-point voltage balance control for three-level T-type inverter is also applied. Finally, the availability and performance of the proposed of open-circuit fault tolerant control are verified with the laboratory prototype. |
