It is not clear what you mean by "overall inductance". The equivalent circuit of a transformer referred to its primary has the magnetizing inductance across the lines and its leakage inductance in series with input. Hence, increase of leakage inductance causes increase of total inductance as seen from input. In fact several inverter designs use the controlled value of leakage inductance to create a low pass LC filter for the ac output voltage without using a separate physical inductor.

@ Sujit...

First of all thanks for your quick comments.

 I already have sent you personal message,

Please can you check,

thanks

Negligible leakage flux, due to low reluctance path offered by CRGO core and low magnetizing current, would not make any considerable change in generated voltage or the power out put of transformers, if utilized......

Dear Prof. Bhupendra Desai.

Thank you very much for your comments.

Please can you share your private email address, I have few further Questions, related Transformer and inductor design.

Thanks
