Control loop stability Innoswitch3-EP
We testing an Flyback 24V/60W with high line input. We saw that the device always change the operation point.
In the first part of the measument, the current could be higher, in the second part the current should be lower. The
change of the operation point is relatifly large. I couldn't find much how could we adjust the control loop. The voltage
overshoot is higher as normal (additional inductance of the current measurement). We saw a D-part parallel to the high
side resistor of the voltage divider, but no informations about it. Do you have an idea how could we optimize the control
