When I am synchronising the PWM Rectifier with the Dual Active Bridge Converter and the Inverter, the current becomes highly distorted. However, the output current and voltage as well as the intermediate stage voltages are perfect as per my design. I have tried several PWM techniques- the abc-dq-abc transform technique, the Direct Power Control technique. However every time it is the input current which gets distorted.

Dear Partha Sarthy, As per my knowledge, your input current is distorting because that you are using very high frequency transformer. Since due to very high switching frequency, the energy residues in the transformer winding, and so a huge current start flowing which means simply shorted. You need to design a good series inductor for your dual active bridge, so that during switching, the energy transfers from transformers to inductor and ZVS phenomeno occur.
