Defibrillator with bias generation circuit utilizing diode power rectification

A defibrillator with bias generation circuit utilizing diode power rectification, comprising:

• a bias generation circuit, comprising:
• a switching regulator, wherein a 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 rectified to create a regulated DC voltage which powers a microcontroller that is in control of a solid-state therapeutic defibrillation waveform generator;
• one or more secondary windings of the transformer whose energy is rectified by a diode, wherein the rectified energy is used to supply one or more bias voltages to the solid-state therapeutic defibrillation waveform generator;
• and
• the diode;
• the solid-state therapeutic defibrillation waveform generator that is configured to create one or more therapeutic defibrillation waveforms;
• an ECG frontend interfaced to the microcontroller and configured to sense cardiac signals, wherein the one or more therapeutic defibrillation waveforms are created based on the sensed cardiac signals;
• and
• a self-contained module that comprises the bias generating circuit, the solid-state therapeutic defibrillation waveform generator, and the ECG frontend, wherein the self- contained module is potted with an insulating material.
