Lowering the Voltage to the Primary will reduce the XL on that Primary winding, resulting in a higher current flowing within the Series circuit - yet it would be difficult to push the needed 6.6 Amps through this Primary winding, as it would act like a Linear Reactor or "Choke" coil, plus result in a very high Secondary Voltage with an open Secondary circuit.

i know the voltage will reduce on the secondary side, but would the voltage not be increased by the ccr compensating for the increased impeadance in the secondary to regulate the 6.6 amps?
