I am working on the simulation of a Solid State Transformer.It has three modules- the PWM rectifier, the Dual Active Bridge Converter and the Inverter.The modules work well individually but the input current gets distorted with the whole system.Why??

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.

please can you send me the model of solid state transformer ? . because i need it in my graduation project in freedm system and i want to make a model of solid state transformer . i searched on the internet but i didnot get any thing . thank you

if you have completed your project and designed model of Solid State Transformer,then can you help me with the simulink model???

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.
