“…1,2 There are mainly two types of DC circuit breakers that may satisfy the interruption requirements of the system: one is the mechanical DCCB which interrupts the fault current by a high-speed mechanical AC switch and a forced current zero circuit; the other is the so called hybrid DC circuit breaker with mechanical-and solid-state switch. [3][4][5][6] In both the mentioned DCCBs, there are mechanical switches, which are required to be opened to a certain distance 2-5 ms after the DC fault happens.…”

In order to meet the fast operation demands of DC circuit breakers, a high-speed vacuum mechanical switch (VMS) driven by a repulsive force actuator is focused. To improve the drive speed and energy conversion efficiency (ECE) of the actuators, the dynamic characteristics of the double sided coil repulsive force actuators are investigated, and two generalized optimization design methods focusing on the aspect ratio of the driving coils (defined as ARF) and the electrical parameters (defined as EF) are developed. FEM simulation models' simulation and tests of VMS prototypes are conducted to verify the optimization methods. Results prove that the ARF method could improve the ECE of a VMS from 1.05% to 7.55%, and EF method could improve ECE of the same VMS from 1.05% to 6.61%, the combination of ARF and EF could improve the value of VMS's ECE to 10.50%, thus proving the validity and accuracy of the optimization methods.

“…The sub-module capacitors are also large and bulky. When half-bridge sub-modules are used, the converter is not able to block DC fault [14] which is a desirable feature for VSC-HVDC converters as DC circuit breakers for high power applications are still under development and are extremely costly [15,16]. An MMC with full-bridge submodules can operate in the presence of a DC fault, but the conduction loss is considerably higher as the number of semiconductor devices in conduction is doubled.…”

This paper presents a new hybrid VSC topology (the StarSwitched MMC) -suitable for HVDC applications. The basic structure and operating principles of the topology are described. Control strategies that regulate the power exchanged between the VSC, the AC network and the DC network are presented. A modulation strategy ensuring appropriate switching of the individual chain-link submodules and a capacitor voltage balancing algorithm that ensures the capacitor voltages are maintained within the required tolerance are discussed. Results from a simulation model are presented to validate the expected performance of the converter and the proposed control schemes.

“…HVDC circuit breakers are a critical technology for managing faults in MTDC networks. DC current breaking however is much more challenging than AC systems because there is no natural current zero-crossing to isolate the fault [4]. The rise rate of short circuit currents in DC networks is also much higher due to the lower system impedances.…”

High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels. Superconductor materials are ideal for DC networks: they do not incur losses operating with pure DC current. This paper will focus on the interface between the superconductor element and the other elements of the breaker, i.e., the mechanical switch and semiconductor elements. A 10 kV DC circuit breaker will be developed based on the optimized interface and control strategy.
