Are you sure you about the serial or do you mean parallel ?

The bridge rectifier drops the voltage, it converts AC to DC you connect both outputs in series run it through the rectifier and 72v out the other side in DC.

You need capacitors to clean up the DC.
I think you need to re visit this as I don't think you understand it. It is also misleading for others.

Doddy is correct.
