Latest Patents

Xiaokun He holds a patent titled "Topology of series-connected MMC with a small number of modules." This invention focuses on a topology that consists of a three-phase bridge circuit, half-bridge valve strings, a three-phase filter inductor, and a three-phase grid frequency transformer. The design requires only two half-bridge valve strings, which significantly reduces the number of submodules compared to conventional MMC structures. This innovation not only achieves the same high DC voltage output but also enhances the power density of the MMC, stabilizes three-phase AC output voltage, and balances capacitor voltages in the half-bridge valve strings. The new topology can reduce the number of submodules by nearly two-thirds and offers a greater AC-DC voltage transfer ratio, leading to lower costs, reduced device size, and improved power density.
