The hot topic for those who owns DX200 welder and willing to participate in re-implementing of the original PowerModule on discrete elements.
This is continuation of the discussion and efforts already put into at other forum: Miller Boost Circuit Board Assembly NO. 200841
This is a restoration project attempt of reproducing using discreet components an obsolete power module which SkiiP 33NEC125T2 no longer produced by SEMIKRON.
DISCLAIMER: This is a high voltage project DANGER. Anyone who joins this experimental project need to be aware of high voltage (up to 1000v) and high currents (up to 100A) which is a high risk and requires to be qualified to work with such circuits and can be done only at your own risk.
