52Split-phase electric power — A split phase electricity distribution system is a 3 wire single phase distribution system, commonly used in North America for single family residential and light commercial (up to about 100 kVA) applications. It is the AC equivalent of the… …
53Compressed-air energy storage — (CAES) refers to the compression of airto be used later as energy source. At utility scale, it can be stored during periods of low energy demand (off peak), for use in meeting periods of higher demand (peak load). Alternatively it can be used to… …
54Solar inverter — Internal view of a solar inverter. A solar inverter or PV inverter is a critical component in a Photovoltaic system. It performs the conversion of the variable DC output of the Photovoltaic (PV) modules into a utility frequency AC current that… …

56Nuna — For other uses, see Nuna (disambiguation). Nuna 3 at Circuit Park Zandvoort Nuna solar racer Nuna 1 (2001) Nuna 2 (2003) …
57Compressed air energy storage — Conceptual representation of the compressed air energy storage concept. Off peak (low cost) electrical power compresses air into an underground air storage “vessel” (the Norton mine), and later the air feeds a gas fired turbine generator complex… …
58Third rail — For other uses, see Third rail (disambiguation). Third rail at the West Falls Church Metro station near Washington, D.C., electrified at 750 volts. The third rail is at the top of the image, with a white canopy above it. The two lower rails… …
59Bond graph — A bond graph is a graphical description of a physical dynamic system. It is an energy based graphical technique for building mathematical models of dynamic systems. A bond graph depicts the energy flow between components used to model a system.… …
60Insulated-gate bipolar transistor — The insulated gate bipolar transistor or IGBT is a three terminal power semiconductor device, noted for high efficiency and fast switching. It switches electric power in many modern appliances: electric cars, variable speed refrigerators, air… …
