The process of assembling the International Space Station (ISS) has been under way since the 1990s. Zarya, the first ISS module, was launched by a Proton rocket on 20 November 1998. The STS-88 Space Shuttle mission followed two weeks after Zarya was launched, bringing Unity, the first of three node modules, and connecting it to Zarya.
Powerpack (drivetrain) Powerpack removal of an M75 APC. A powerpack or power pack is a part of a modular powertrain that contains some type of engine (most frequently an internal combustion engine, but other types, including electric motors, are possible) and may also contain a transmission and various supporting components.
A switched-mode power supply ( SMPS ), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains ...
A stepper motor, also known as step motor or stepping motor, [1] is an electric motor that rotates in a series of small angular steps, instead of continuously. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased, creating continuous ...
Tesla installed 400 Powerpack-2 modules at the Mira Loma transformer station in California. The battery storage serves to store energy at a low network load and then to feed this energy back into the grid at peak load. The principal way of adding peak generation capacity prior to this was the use of gas-fired power stations.
A structure chart (SC) in software engineering and organizational theory is a chart which shows the breakdown of a system to its lowest manageable levels. [2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as SoH, and SoC), calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it.
A power module or power electronic module provides the physical containment for several power components, usually power semiconductor devices. These power semiconductors (so-called dies) are typically soldered or sintered on a power electronic substrate that carries the power semiconductors, provides electrical and thermal contact and ...
