Fig 2: MMC Submodule Mode (a): When S1 gets turned on, diode D1 is forward biased and terminal voltage is … 網頁The Half-Bridge MMC block implements a half-bridge modular multilevel converter. The converter consists of multiple series-connected power modules. Each power module consists of one half-bridge and one capacitor on the DC side. You can choose from four model types: Switching devices — The converter is modeled with IGBT/diode pairs.
網頁2024年3月24日 · This paper presents a silicon (Si) and silicon carbide (SiC)-based hybrid modular multilevel converter (H-MMC) comprising a combination of half-bridge and full-bridge sub-modules (HBSMs and FBSMs) with a novel voltage sorting scheme. In addition to the fault blocking capability, the proposed H-MMC achieves improved device utilization … 網頁2024年7月10日 · Finally, we set up a 9 level full bridge MMC-HVDC simulation system in PSCAD/EMTDC. The charging strategies are simulated, and the results show that the proposed control strategy is feasible.
網頁2024年5月1日 · Unlike full-bridge MMC (FB-MMC) and clamp double sub-module MMC (CDSM-MMC), HB-MMCs are defenceless against DC side faults. Different types of DC circuit breakers (DC CBs) assisted with arrester banks/damping resistors such as solid-state CB and hybrid DC CBs can be used to interrupt the DC fault current. 網頁The predictive sorting algorithm (PSA), used for half-bridge MMCs, is one method which helps to achieve a compromise between the two. For HVDC application, though, the MMC may consist of full bridges (FB) in order to handle DC faults. Hence this paper proposes an extension of the PSA for its use in full-bridge MMC (FB-MMC).
網頁2024年4月11日 · Abstract: Unidirectional current H-bridge modular multilevel converter (UCH-MMC) is a variant of full-bridge MMC and uses fewer semiconductor devices. The operating area and operation mode of UCH-MMC differ from those of conventional half-bridge MMC (HB-MMC) because of the unidirectional current and bipolar voltage of UCH …
