soft switching push pull converter (need help..)

Hi everyone..
I have designed a soft switching push pull converter using for IGBTs..
The problem is the circuit keep on short circuited. The transformer is
winded by myself and it is center tapped for primary and secondary
windings. it has a ratio of 1:1.

For the load side, which is consist of an L and C formed by the low
pass filter. Do i need to ground the load side?
What are the maybe the causes for my short circuit?
Thanks..
