A capacitive discharge stun-gun uses a flyback output circuit in which a semiconductor switch operates under control of a controller or suitable logic circuitry. The flyback circuit can deliver 50-65 kV pulses to a pair of electrodes in order to ionize air adjacent a target in order to initiate good electrical contact. When the electrodes are in good contact with the target, the flyback circuit delivers current at a lower voltage. In one mode of operation the stun-gun is controlled to initially deliver wider pulses optimized for causing air breakdown and to then deliver a series of shorter pulses in pulse groups optimized for causing involuntary muscle cramping.
