ELECTRON VOLTAGE COMMUTATOR Russian patent published in 2003 - IPC

FIELD: electronics. SUBSTANCE: invention refers to commutated power supplies in which commutation of both supply buses by electron intellectual key incorporating unit forming status of key state and enabling signal ( status ) to be formed with break of load circuit in absence of control signal or in case of short-circuit or in absence of current through load in closed state is required. Electron voltage commutator includes first and second intellectual keys, first and second resistors and unit controlling status. Voltage across closed keys gets half as much due to insertion of two resistors and serviceability of electron voltage commutator is established thanks to insertion of technological keys without disturbance of connection of load unit which raises commutator reliability. EFFECT: raised functional reliability of electron voltage commutator. 1 cl, 2 dwg, 1 tbl
