1. The combination comprising:

  • a main power source operable to provide an AC voltage at an output;

    an inductor means and a capacitor means effectively series-connected across the output, the inductor means being resonant with the capacitor means at or near the frequency of the AC voltage;

    load means effectively connected in parallel with the capacitor means, the load means requiring conditioning before being operable to effectively absorb power, the load means having an auxiliary input adapted to receive power operable to effect the required conditioning;

    an auxiliary power source connected with the auxiliary input and operable to provide power thereto, thereby to effect the required conditioning; and

    means operable to prevent the main power source from providing the AC voltage at the output until after the auxiliary power source has provided power to the auxiliary input for a pre-determined period of time.
