DEVICE AND TECHNIQUE OF DESTROYING DIELECTRICS AND SEMICONDUCTORS Russian patent published in 1995 - IPC

FIELD: destruction of dielectrics and semiconductors. SUBSTANCE: with the object exposed to a combined action of varying frequency current and its pulses, the high- voltage pulse is sent at the moment when the speed of the change of amplitude of a.c. exceeds 0. The device under review has a source of varying frequency current, current sensor, comparator, switching device, high-voltage pulses generator, electronic system with high-voltage and earthed electrodes. The device is supplemented with inductive filter whose isolation is equal to the value of the high-voltage pulse. EFFECT: higher efficiency and reliability. 2 cl, 1 cl, 3 dwg
