ABSTRACT:
An electric power supply operates to supply electrical energy to an electronic device implanted within a living body. The electric power supply has a capacitor which is used as the principal power source. A voltage regulator, overvoltage inhibitor, and a diode are cooperatively arranged to couple the capacitor with an induced voltage source used to charge the capacitor. The diode prevents the capacitor from discharging through the charging circuit when capacitor charging is not taking place. A regulator is used to control the electrical energy that flows to the electronic device. In one form of the electric power supply, a make-before-break switch unit is used to alternately connect the electric device with a charged capacitor or a battery power source so as to provide continuous electrical energy to the electronic device.
