ABSTRACT:
The capacitor of a defibrillator is charged to a high D.C. voltage from a low voltage D.C. source of small capacity by an inverter, a transformer, and a rectifier coupled in sequence. The turns ratio of the transformer is changed as the voltage across the capacitor reaches predetermined levels and the current in the primary of the transformer is regulated by comparing the voltage drop across a small resistor with the voltage of the source.
