Power electronics for a 1-kilowatt arcjet thruster. The preliminary development and demonstration of new, high efficiency, power electronic concepts for start up and steady state control of dc arcjets is reported. The design comprises a pulse width modulated power converter which is closed loop configured to give fast current control. An Author: R. P. Gruber. Power electronics for a 1-kilowatt arc jet thruster. modulated power converter which is closed loop configured to give fast current control. An inductor, in series with the arcjet, serves the dual role of providing instantaneous current control, as well as a high voltage arc ignition pulse. Tests with arcjets demonstrate that the power Author: R. P. Gruber.

An electrically-powered spacecraft propulsion system uses electrical, and possibly also magnetic fields, to change the velocity of a of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed.. Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate. About Power Electronics Books. We have compiled a list of Best & Standard Reference Books on Power Electronics Subject. An exploration of the state-of-the-art in power conversion techniques and power semiconductor devices, this Books are the bottom-down approach, covering the characteristics of power semiconductor devices first and then the fundamentals of conversion techniques. Power electronics for a 1-kilowatt arc jet thruster After more than two decades, new space mission requirements have revived interest in arcjet systems. The preliminary development and demonstration of new, high efficiency, power electronic concepts for start up and steady state control of dc arcjets is reported. the low-power DC arcjet thruster performance. In the present study, arc voltage, thrust and other important pa-rameters of arcjet thruster are measured for various mass flow rates of argon, nitrogen, nitrogen/ammonia mixtures simulating hydrazine, while the arc current of the arcjet thruster is fixed constant (i.e. I=10 A), so that the effects.
