Title: Method for delivering defibrillation energy

Abstract: An automatic external defibrillator ("AED") is described that includes a high voltage delivery circuit for producing a biphasic electrical pulse to defibrillate a patient. The delivery circuit includes a plurality of capacitors controlled by IGBTs. The bridge circuit has four SCRs which are selectively switched to produce, for example, a biphasic steering of current.
