Superimposed Voltage Over Existing DC pulse Power circuit?

Pulsing 12v DC circuit with inductor has sufficient current, but too low voltage to 10 ohm load. Can an added superimposed much higher voltage inserted parallel with inductor, ( from 2 inductors wound together inductive transfer) help the main circuit? ( Capacitive coupling type with no core) This may be called crossover leakage induction voltage from the second source, of very low power/current, way higher volts. Meter reading shows 100-200 volts transferred and available, but not tested with load yet for voltage final transfer.
Power supply is isolated of separate ground than 2nd source ground.

A coil and series condenser has resonance and raises 12v up to 250-300v on the old car distributors for primary + secondary ignition. That's why the condenser was printed rated for 600 volts, even though the auto battery was 12v.

If a separate inductor was used for back EMF voltage, that only applies during the off time of power supply and can't be used.
Looking for suggestions/comments, besides any 400 watt power inverter box.

The earlier technicians had told of demonstration of transfer from double coils like that (WITHOUT MENTIONING VOLTAGE) that inserted reactance ohms in the line of 12v battery to load of 20 amp draw that caused higher in series ohms that reduced current on meter to 12 amps. Same grounds used. I heard that design was also used on large motors to slow them down.
