High Power Current Limiting Circuit. Potentiometer r5 was adjusted to set the current limit a little above 1 a. I looked around and the max is up to 10a only.
The load resistor was. Operational amplifiers can be used as differential amplifiers to give the required voltage reference drive for the output devices. Some electronic circuits employ active current limiting since a fuse may not protect solid state devices.
Some electronic circuits employ active current limiting since a fuse may not protect solid state devices.
Therefore a high input voltage supply or current limit can cause very high power dissipation in the high side switch during current limiting. Some electronic circuits employ active current limiting since a fuse may not protect solid state devices. At 300 volts and 4 amps you are trying to get 1200w of power out of this circuit. If this power dissipated in the switch causes the operating temperature to rise above the thermal shutdown threshold tsdthen the switch will turn off to protect itself and the load further downstream.
