ELECTRIC-CIRCUIT ARCLESS SWITCHING DEVICE Russian patent published in 2002 - IPC

FIELD: electrical engineering; off-line power supply systems. SUBSTANCE: device has contacts and controlled semiconductor switch such as static inductance transistor whose control electrode is connected to first contact lead that forms first output terminal; second contact lead is connected to first power lead of semiconductor switch and forms second output terminal; control electrode of semiconductor switch is connected to first contact lead through diode; inserted between first power lead of semiconductor switch and its control electrode are parallel-connected capacitor and resistor. EFFECT: enhanced reliability due to eliminating short arc across contacts. 1 cl, 1 dwg
