Various time step errors for a DC-DC converter circuit

I am working with a full bridge rectifier dc-dc  converter. I am recieving errors that the time step is too small. I followed the help instructions and the problem is not fixed. The time step too small error comes up for different reasons depending on where the time step is set. I have recieved "Trouble with( ideal_diodes_virtual)....", problems at various nodes ex."$13", and  "trouble with (md3.xs2)d4.xs2". I utilize mosfets switching on a 10us cycle on the primary. Could this be to fast. Everytime I change a analysis setting the simulation changes its actual run time, but I still get error around 6 ns. I can not run this simulation longer than that. Please help.

Hi,

 

I can try to help you with this problem but I need the circuit file.
