New type of vacuum switching tubes has been designed in FGUP VEI, which effective used at long pulse duration or in direct current operation mode. Small losses and high efficiency of switching are reached due to careful formation of an electron flow in a beam and electrons deceleration at approach to the anode. This type of tubes was named Electron Beam Valves (EBV). As a result of researches have...
Static VAR Compensators (SVC) on the basis of semiconductor devices have been developed and introduced in power industry and in transmission lines. SVC provide control of active and reactive power in the system. SVC are based on converters and operate at voltage level 35 - 110 kV. Researches and development in FGUP VEI of high-voltage vacuum switching tubes with small power losses has allowed to start...
A brief review is given of various types of devices for converting heat or radiant energy directly into readily available electrical form. These devices include the thermoelectric generator, the photovoltaic cell, the thermionic converter, and the photoemissive converter. The discussion is from the point of view of possible space-vehicle application. An attempt is made to indicate in a general way...
