英文摘要： Indirect matrix converter (IMC) is a novel direct AC-AC power converter with high quality input/output waveforms, bi-directional power flow capability and compact structure. IMC is very suitable to feed multiple motors. In this project, a multi-output IMC will be applied to constitute a novel multi-drive system. The operation mechanism of this system will be investigated under different working conditions (with different power flow or fault cases). Furthermore, the researches on this system will be carried out through the improvement of conventional modulation strategy, the applications of novel control methods and the fault-tolerant operation. Based on these works, the optimal control strategies will be proposed, which include the coordination control algorithm considering both the power quality at grid side and the motor drive performance, the finite control set based model predictive controller, the mode switching technique between normal operation and fault-tolerant operation and the fault-tolerant control strategy. The final destination of this project is to achieve a multi-output IMC based multi-drive system with high performance, high efficiency, high reliability, high power density, perfect functions and good extendibility, which will promote the development of adjustable-speed drive technologies.
