Defibrillator utilizing a multi-winding transformer

A defibrillator utilizing synchronous 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;
• the primary winding of the transformer, wherein a synchronous rectifier is used across a primary side of the transformer;
• and
• one or more secondary windings of the transformer whose energy is rectified, 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 one or more therapeutic defibrillation waveforms;
• one or more drivers configured to switch the bias voltages before the bias voltages are supplied to the solid-state therapeutic defibrillation waveform generator;
• and
• the solid-state defibrillation waveform generator that is configured to create the therapeutic defibrillation waveforms utilizing one or more of the bias voltages.
