Thyristor overcurrent protection circuit 4
Source: InternetPublisher:公子李 Keywords: Protection circuit thyristor overcurrent protection BSP Updated: 2021/07/12
This circuit is used
in the driving voltage stabilized power supply protection device. The protection operating
current is 2A (the thyristor is turned on when the control electrode voltage is about 1V
), and the reaction time is several microseconds.
Resistor Rz and diodes VDi and VD2 can protect
the thyristor
control electrode
from damage caused by excessive current and voltage . SB is the reset button after the fault is eliminated
.
