A three-phase motor is more compact and less costly than a single-phase motor of the same voltage class and rating, and single-phase AC motors above 10 hp (7.5 kW) are uncommon. Three-phase motors also vibrate less and hence last longer than single-phase motors of the same power used under the same conditions. [32]
Three-level converters can synthesize three (instead of only two) discrete voltage levels at the AC terminal of each phase: + 1 / 2 U d, 0 and - 1 / 2 U d. A common type of three-level converter is the diode-clamped (or neutral-point-clamped ) converter, where each phase contains four IGBT valves, each rated at half of the DC ...
CSC's former headquarters in El Segundo, California, USA (branch office after 2008). Computer Sciences Corporation (CSC) was an American multinational corporation that provided information technology (IT) services and professional services.
In 1979, even after the introduction of the Z80 and 8085 processors, five manufacturers of the 8080 were selling an estimated 500,000 units per month at a price around $3 to $4 each. [ 23 ] The first single-board microcomputers , such as MYCRO-1 and the dyna-micro / MMD-1 (see: Single-board computer ) were based on the Intel 8080.
Bokaro Steel Plant gate. Bokaro Steel project, which is now in Jharkhand after the bifurcation of Bihar in 2000, was planned in the late 1950s. The political elites of Bihar then argued for a case for building a steel plant in Bokaro as Bihar was backwards in terms of industrialisation and the area where the steel plant was proposed was rich in mineral resources required for making steel as it ...
