Hi, I've designed a boost converter with UC3842.
You see the electrical circuit below.
The problem is that the output should be set to 21 volts, but the output goes to much higher values.
Circuit Profile:
VIN (min)=9v
VIN(max)=18v
VIN(nom)=12v
VOUT=21v
Iout(max)=0.6A
fsw=344KHZ
At all, feedback has no effect on the output of the circuit.
This circuit is closed in the Multisim software
Thank you for helping me find a defective circuit.
