Abstract: A source-network coordination type direct-current (DC) circuit breaker based on pre-charged capacitors for an MMC based DC grid is provided. The MMC based DC grid is provided with four converter stations, each having two converters, which are in loop connection through a double-loop DC overhead line. Two ends of each DC line connecting the converters are separately equipped with DC circuit breakers for isolating a fault of the DC line. An MMC active voltage adjusting control strategy is matched with pre-charged capacitor voltage in the self-adaptive mode to provide a beneficial breaking condition for a quick mechanical switch branch, so that the fault line is effectively cut off.

Abstract: Optical elements including YbF3 layers with high transmittance in the LWIR spectral range are described. The YbF3 layer is produced by an ion-assisted deposition process under high voltage conditions. Dense, uniform, and nearly defect-free YbF3 layers are formed.
