A modular multilevel converter (MMC) includes multiple converter arms, each converter arm having: N submodules connected to each other in series, N being an integer equal to or greater than 2; and a circuit opening unit connected to the N submodules in series to open a circuit of the converter arm, wherein the N submodules has n submodules including full-bridge circuits and N−n submodules including half-bridge circuits, n being less than N.
摘要:
The present invention relates to a jawbone distraction system and control method thereof, including a jawbone extension apparatus, a remote controller and a monitor, the jawbone distractor being configured to allow a horizontal shift of alveolar bone as well as performing vertical jawbone distraction, being precisely controlled in a wireless mode and configured to control a drive of the jawbone distractor through the remote controller while ascertaining a driving state by the monitor.A jawbone distraction system, including a micro-actuator and an actuator controller controlling the micro-actuator, being formed to include a jawbone distractor installed to an upper bone and a lower bone connected to the upper bone and configured to adjust an interval between the upper and lower bones, and a monitor generating and wirelessly transmitting an actuator control signal to the jawbone distractor, is further comprised of: a remote controller including a forward shift key and a reverse shift key that set the micro-actuator to shift each in a forward direction and a reverse direction, in which the monitor is configured to include an arithmetic processor generating an actuator control signal in response to a forward shift key signal and a reverse shift key signal that are received from the remote controller. The actuator controller includes an actuator state detector detecting a voltage of a device serially coupled to the micro-actuator or a current signal of an input node of the micro-actuator as a state detection signal.
