FIELD: heavy-current semiconductor electronics; laser and accelerator engineering. SUBSTANCE: high-voltage switch has starting unit, resistor, capacitor, two reversible-dinistor units, two nonlinear components with saturable cores; first component is, essentially, reactor connected to anode of first reversible-dinistor unit, second one is connected to anode of second reversible-denistor unit; first lead of capacitor is connected to cathodes of both units. Novelty is that two diodes, additional capacitor, inductive component, demagnetizing windings of nonlinear components are introduced in high-voltage switch; second nonlinear component is made in the form of step-up transformer; starting unit is connected in parallel with its primary winding and its positive lead is connected to starting lead of this winding; transformer secondary winding is inserted between anode of first diode and anode of second reversible-denistor unit; starting lead is connected to anode of first diode; reactor demagnetizing winding, resistor, inductive component, transformer demagnetizing winding are interconnected in series and parallel-connected to additional capacitor inserted between anode of first diode and cathode of second diode; cathode of first diode is connected to second lead of capacitor, to anode of second diode, and to reactor. EFFECT: improved reliability of switch due to regulation of magnetic state of its nonlinear components; reduced voltage across starting unit components. |
