[Abstract]:As a new type of high-voltage and high-power topology, modularized multilevel converter (MMC) has not only gained wide attention in the field of direct current transmission, but also has a great application prospect in the field of high-voltage frequency conversion. Compared with the traditional high voltage converter topology, the modular multilevel converter shows a series of technical advantages in the aspects of flexibility, reliability, voltage waveform quality, input transformer design, voltage power level, etc. In order to promote the development of high voltage frequency conversion technology in China, the circuit characteristics, submodule structure, modulation method, capacitive voltage balance strategy, harmonic analysis, circulation suppression, start-up precharge, fault tolerance and reliability of MMC inverter are discussed. The latest research progress in low frequency operation is reviewed in detail, and the difficulties and challenges of modularized multilevel high voltage frequency conversion technology are pointed out.
