Title:
PULSE POWER SUPPLY DEVICE SWITCHING CONTROL CIRCUIT AND PULSE POWER SUPPLY DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/026084
Kind Code:
A1
Abstract:
Disclosed is a switching control circuit for controlling a switching unit included in a pulse power supply device. The present invention measures current supplied from a switching unit to a load to sense whether or not an arc occurs, and when the arc occurs, generates a turn-off control signal for turning off semiconductor switches included in the switching unit by a switching control circuit, and outputs the turn-off control signal to the semiconductor switches, then, after a predetermined time, generates an additional turn-off control signal and outputs the same to the semiconductor switches, thereby solving the problem of the prior art in which turn-off operations of the semiconductor switches are not properly performed due to an influence of noise, so that the present invention has a highly reliable effect of protecting the semiconductor switches included in a pulse power supply device.
