Abstract

A high voltage array switching system utilizes an array of low voltage charge storage devices to generate a relatively high energy, high voltage output required by battery powered devices such as implantable cardioverter defibrillators. The system includes a low voltage battery system having a supply voltage connection and a ground connection. N low voltage charge storage devices are provided, with each charge storage device having one of an anode and a cathode electrically connected to the supply voltage and having the other of the anode and the cathode electrically connected to the ground connection. M configuration switches are electrically connected between the charge storage devices and the battery system. A control system selectively controls the configuration switches to charge the charge storage devices in a configuration in which at least some of the charge storage devices are in parallel and discharge the charge storage devices in a configuration in which at least some of the charge storage devices are switched to be in series. In the system, the number N of low voltage charge storage devices is greater than four and is also greater than or equal to M, the number of configuration switches.
