push pull converter 12Vdc to 310 V dc drain voltages problem,im confused
im trying to get 310volt dc from 12 v dc. im using push pull topology. i have some strange signals on drains of the mosfets when i try to rectify the ac output of the transformer.
when i connect a load directly to the transformer ac output, drain voltage and gate signal are like on the pictures 1 .
but when i rectified the ac output of the transformer with bridge configuration(4xfr107 diode) and connect the same load drain voltage and gate signal are like on the pictures 2
in picture 3 and 4 are drain voltages with the load connected directly to output of the transformer without rectified (picture 3) and load connected to the rectified output of the transformer (picture 4 )
what can be the reason for this?
