As the increasing penetration of modular multilevel converter (MMC)-based high-voltage direct current (HVDC) into bulky power transmission systems, the performance of MMC on dealing with DC faults, especially on

All of these services depend on the control system design of the grid side converter, in this case a MMC converter. Depending on the circumstances, it may be more advantageous to use a voltage or current control, a PLL based synchronization or a virtual inertia emulator, etc. There are a ...
It requires less space and has less footprint and weight of the converter than LCC. Therefore, offshore wind power plants which need a DC cable connection prefer VSC-MMC technology. (10) It can change current and power flow direction without reversing the polarity. Power switches in VSC-MMC...

we forgo the use of a DC–DC converter and instead developed a custom microchip that can operate directly from the BFC. The integrated circuit was engineered from the ground up to consume less than a microwatt on average (~0.4 µW) via a voltage-to-frequency conversion scheme together...
This paper is organized as follows: initially, a brief review of the topologies considered as the most suitable for PFC battery chargers is shown, and then the selection criteria that lead to the choice of the cascaded converter topology that will be implemented. Then a loss analysis is perfor...
1 as an example, the DC grid is divided into two parts by a DC-DC converter. The upper part C1-C4 is a cyclic and radiation mixed connection structure. The lower part is a point-to-point DC system. Obviously, the normal operation of the whole network will be hardest hit if the ...
Distributed Two Stages DC/DC + DC/AC converter: (Figure 8e): This is an improvement over the centralized topology, connecting each pack in parallel to a DC bus, and using a DC/DC converter to equalize the voltage between packs, thereby resolving differences in the drawable current. - Distr...
