Abstract
A defibrillator includes a module having a portion of the high-voltage components of the defibrillator attached to a substrate and encased in a dielectric material. In one embodiment the defibrillating shock is delivered by a high voltage H-bridge circuit which utilizes four controllably switched semiconductor devices such as IGBTs.
