Hi, I am building this smps (schematic attached ) I have a question, since it's a half bridge topology the other end of the transformer primary is attached to half the mains rectified (capacitor middle) via a capacitor ,
but here's the question , the transformer primary is attached via a capacitor to the middle point of the smoothing capacitors which makes now two capacitors in series to ground and to +ve, if I am correct that makes the maximum voltage attainable at the primary not half but 1/4 that of the mains rectified correct?
can I just connect the float from the primary directly inbetween the smoothing capacitors without the additional capacitor ?
my devices are IRFP 460 they handle up to 400v if i remember correctly.
