1. A defibrillator with bias generation circuit utilizing bridge power rectification, comprising:
a bias generation circuit, comprising:
a switching regulator, wherein switched output of the regulator is connected to an input of a primary winding of a transformer and wherein an output of the primary winding of the transformer is utilized to supply a regulated DC voltage which powers a microcontroller that is in control of a solid-state therapeutic defibrillation waveform generator in an H-bridge configuration;
one or more secondary windings of the transformer whose energy is rectified by a bridge rectifier, wherein the rectified energy is used to supply one or more bias voltages to the solid-state therapeutic defibrillation waveform generator that is used to create a therapeutic defibrillation waveform; and
the bridge rectifier.
