Hi everyone, i bought STEVAL-ISA147V3 to understand well D-SMPS. At first try, i didn't connect fan to output load, so the fuse blow and some diodes at PFC circuit (D9, D12 and D13) become short-circuit . Then, i realized i should connect load to output, so i connect cooling fan which you send with STEVAL-ISA147V3. Actually it worked very well, everything was okey untill re-start. Unplugged the STEVAL-ISA147V3 and plugged again. But the fuse blow again and same diodes become short-circuit again. I've read the getting started document of STEVAL-ISA147V3 but i couldn't see any tips about starting except connecting a load. What should i do except connecting a load at starting? Thanks for help.
