摘要
In high-power applications such as medium-voltage (MV) drives, multilevel voltage-source converters are widely used today. On the other hand, the study on matrix converters (MC) has primarily been limited to the low power range. Aiming to combine benefits from both multilevel structure and direct power conversion, this article investigates the topologies and operating principles of multi-modular matrix converters (MMMC). Built from three-input two-output matrix converter (3x2 MC) modules, two versions of MMMCs are presented and studied. Modulation schemes to synthesize sinusoidal waveforms on both ac sides of the converters are discussed in details. Featuring a modular design, relatively low switching frequency and use of low-voltage power devices, the presented MMMCs target higher power applications where four-quadrant operation and fast dynamic response are expected. The validity of the study is verified by simulation results.
