Hello Need your advice. my SMPS scheme works well as long as the input voltage is constant. 90Vdc. when I connect to the wind power systems running within a few minutes and break through Tranzistor volatile wind power voltage from 40V to 160V. 250w load. Transistors very hot Does this scheme...

maybe a little bit outside the forum topic. I decided, your schemes do pcb battery charge controller. vipper22a scheme with input voltage 40-180vdc. the total battery voltage 48v. loading 48-60vdc counting down transformer with ExcellentIT 7300

Hello. I do the battery charger according to this scheme. I asked for help, because initial start scheme extremely hot transistors. maybe what's wrong in the scheme. Transistors IRFP450 Thanks
