Abstract: The present disclosure discloses a sub-module hybrid MMC with low full-bridge ratio and a DC fault processing method thereof. The hybrid MMC prevents the energy at the AC side from entering a DC system by artificially creating three-phase interphase short circuit at the AC side of a converter in the DC fault processing process, which greatly reduces the ratio of full-bridge sub-modules required for DC fault processing. Moreover, the hybrid MMC has the same DC fault processing speed as the sub-module hybrid MMC with high full-bridge. The duration of the artificially created three-phase interphase short circuit fault in the fault processing process does not exceed 30 ms, which will not have a great impact on the AC system.

Abstract: In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images. If the pause time of pausing satisfies a certain length, a parameter associated with an image compression ratio is adjusted. After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.
