      1000w smps based on LUDO3232

      Hi upik May I ask you where are you going to use this amplifier? Keep a few things in mind that say a proper 3K smps can power a 5K amplifier.

      1000w smps based on LUDO3232

      Hi Upik the maximum power for an EE55 core and material PC40 you can get around 2500 to 2800 watts in full bridge topology.

      Do not forget

      Current trafo

      It could be the case due to the high current involved you can use a low value resistor (current shunt) instead or even a

      I will check the gate voltage of the fets as soon as I get home

      about the current trafo
      The core gets really hot (only when smps is
