Abstract
Apparatus and method for parallel charging of mixed capacitors, including a source for generating a train of high frequency pulses coupled through a pulse transformer, a high speed diode connected to the pulse transformer, a filter capacitor connected to the high speed diode and acting as a low-pass filter for the train of pulses, and a plurality of solid state switches for selectively coupling and decoupling the voltage across the filter capacitor to one of a plurality of capacitor banks which make up the biphasic high voltage defibrillation pulse supply.
