Hello,
I am used a Chroma DC electronic load (63206A-600-420 ) in constant resistance (CR) mode as my PFC's load and the inductor current would always lose control after several seconds of operation.
When I change the load from electronic dc load to real resistor, the converter would always work. This really confused me.
In my simulation, I used a R as converter's load and the system would always work very well.
Do there exists any large difference between CR mode electronic load and real resistors? Thanks!
