US Patent 7474518 Electronic disabling device having adjustable output pulse power

An electronic disabling device with multiple adjustable power levels and a method of providing the same. The electronic disabling device includes an initial step-up voltage circuit coupled to receive an initial power from a battery and a final step-up transformer (e.g., a plain transformer, an autoformer, etc.) adapted to provide an output power. In addition, a power control circuit is coupled between the initial step-up voltage circuit and the final step-up transformer to adjust the power levels of the output power provided by the final step-up transformer.
