ABSTRACT:
A voltage translator for increasing the voltage available from the battery of an electrically energized watch so as to supply power for components requiring higher operating voltages. An inductor is switched into and out of the battery circuit using sharp pulses derived from the watch time base. The energy stored in the magnetic field of the inductor during the charge time is transferred to a storage capacitor as the field collapses. The rapid collapse of the field induces a high reverse voltage in the inductor so that the voltage across the storage capacitor increases after repeated pulses to a predetermined, relatively high value at which time a blocking circuit prevents further pulsing of the inductor, thereby automatically regulating the voltage.
