US12435956 - Methods and apparatus for a high voltage circuit

A conducted electrical weapon (“CEW”) comprises one or more switch devices and a charge storage circuit for delivering a stimulus signal via a deployed electrode. A charge may be stored in the charge storage circuit. A first switch device of the one or more switch devices may be selectively turned on according to the charge of the charge storage circuit. The stimulus signal may be delivered via a current flow path comprising the first switch device and the deployed electrode according to the charge of the charge storage circuit.
