In this work the main consideration of the design of truncated biphasic exponential external defibrillator appear. The equipment is directed to the treatment of cardiac arrest by ventricular fibrillation. The structure of the defibrillator account with two main processes: the charge stage and the discharge stage. For the charge stage is used a Flyback topology controlled to constant frequency with a current sensor in primary and a voltage sensor in secondary of the Flyback transformer. The energy is stored in a bank of capacitors in a time from 6 to 15 sec., according to the defibrillators charge standards. For the discharge stage a H bridge is proposed to handle to high voltages with commercial devices. H Bridge allows to generate the biphasic exponential truncated waveform and to modulate the energy. The results of the proposed approach in a prototype of small signal appear.
