Methods and apparatus for a conducted electrical weapon

A conducted electrical weapon (“CEW”) for providing a current through a human or animal target to impede locomotion of the target, the CEW comprising:

• a processing circuit;
• two deployment units, each deployment unit includes a first wire-tethered electrode and a second wire-tethered electrode for launching toward the target to provide the current through the target to impede locomotion of the target;
• four transformers, one transformer for each electrode of each deployment unit, each transformer including a primary winding and a secondary winding;
• four switches, one switch for each transformer, each switch coupled in series with the primary winding of one transformer respectively;
• a first capacitance coupled to the primary winding of all transformers;
• a second capacitance;
• and
• a third capacitance;
• wherein:
• the secondary winding of each transformer is in series with one electrode respectively so that each electrode is in series with the secondary winding of a different transformer;
• the second capacitance is coupled to the secondary winding of each transformer whose secondary winding is in series with the first electrode of each deployment unit;
• the third capacitance is coupled to the secondary winding of each transformer whose secondary winding is in series with the second electrode of each deployment unit;
• the processing circuit enables the switches coupled to a first transformer and a second transformer of the four transformers to discharge the first capacitance through the primary windings of the first and second transformers, the secondary winding of the first transformer and the secondary winding of the second transformer are in series with the first electrode of any one deployment unit and the second electrode of any one deployment unit respectively;
• and
• responsive to discharging the first capacitance, the second capacitance and the third capacitance discharge through the electrodes coupled to the first transformer and the second transformer to provide the current through the target to impede locomotion of the target.
