@Easy peasy Thanks for the advice. I have zoomed it,But both the voltages are overlapinglooking at the waveforms - you already have it - try zooming in on the edges ...

Just a note - the rail voltage do not match the device ratings - you should correct that either by different devices or by scaling the input bus etc
Why, particularly?I am not able to produce the phase shift b/w the primary and secondary of the coupled inductor transformer.
The fault in post #1 is looking at the wrong voltages. Primary and secondary voltage of an ideal transformer are always in phase. Instead you want to look at the primary and secondary bridge output voltage, respectively voltage at both sides of the series inductor. The current waveform reveals that the circuit is operating with phase shift, by the way.How can I further improve. Where am I going wrong? Are the pulse generator for secondary bridge are wrong? How get the phase shift from primary to Secondary?

Second fault is driving the transistors without dead time. The point has been verbosely addressed in the edited circuits by treez. To get the intended behaviour in the original circuit, it's sufficient to reduce ton of all drivers from 10 µs to 9 µs, keeping all other parameters, also the 10 nF capacitors.

My bad, all this time I was looking at the ideal transformer voltage waveform and wondering why there isn't a phase shift.
