Example Phase Shifted Full-Bridge DC-DC Converter 300W 12V Mode 3 not giving expected results

Dear Sir,
I am using SimCoder module( Phase Shifted Full-Bridge DC-DC Converter 300W 12V) of PSIM. The results of the simulation are not as expected. The PWMs for switches Q2 and Q3 are not getting generated and the output voltage should have been 12 V. I have also checked the other modes of this example. None of them is working as expected. If any changes in the example are needed to be done please let me know !
Thanks and Regards,
Akshay
