Power Flow Controllers (PFCs) or Current Flow Controllers (CFCs) are expected to be required in future High Voltage Direct Current (HVDC) grids.
A reduction of 13 % of the total energy loss on a typical journey can be obtained by optimising the design of the DC/DC converter on a mission profile rather than at nominal power.
The main interest of this Full-Order Nonlinear Control is the possibility to obtain a very high dynamic performance of the MMC power flow.
In this article, the interactions between AC grid and existing VSC control modes are analyzed.
This paper proposes an auxiliary circuit for mechanical type DC Circuit Breakers which enables to use the internal energy of the DCCB capacitor for the line pre-energization.
This article presents the modified Preisach model of hysteresis for a 3-phase medium frequency transformer in a 100 kW dual active bridge converter.
