I'm looking into creating positive square wave sharing same reference ground as primary on the secondary side of a transformer without using a rectifier. Assume that I have ability of providing the top of primary winding with a square wave voltage alternating between 0 V and 9 V.
Would following earthing configuration provide a transformed voltage on the secondary that would alternate between 0 V and 9 x N volts? N is the turns ratio. Primary and secondary share the same ground.
If such configuration is not possible, would a shunt resistor help the situation?
