smps for hybride
First happy newyear.
I have a plan to make a SMPS for the hybride, contains 2x 140 volt 300mA differential 1 x 450 volt 100 mA and 6.3 volt 10 Amp. Maybe in future also 2 x 60 volt 5 Amp.
What I can use best, it can be maybe not easy because of high switchoff induction for driver mosfets, but can snubber that.
I want to use simpel, because some people here make supply,s so complicated that is not nessesary with modern pwm ic.
some examples in pictures, shema.gif is a weld converter for the ones who need a lot power.
So what kind of smps I need, flyback, bridged, half bridge.
I have also a idea to use the power trafo of the mosfets stage, it is 60 volt 5 amp, and make a converter who has 24 80 volt input and the tube voltages as output.
Since you need high voltage at relatively low current, flyback would be best.
for also the 60 volt x 2 and 5 ampere extra then I need a bridge one? but can these also deliver high voltage without problems.
I have made a schematic as example, I can not simulate it with multisim.
Oke, I have use a two mosfet switch for less voltagestress for mosfets I have
high output voltage.
I know there are more things to do like ntc and such.
Let me now what toughts.
very nice site of a guy who torture a switching supply he build.
3 to 60 volts 40 ampere.
if you see it then you think, do that work?
