Battery charger
A battery charger comprises power supply means including an a.c. power source and rectifier means for producing voltage pulses; switching means connected to the power supply means in series with a battery to be charged; control circuit means connected to the switching means for normally disposing the switching means in the conductive state during charging periods of the voltage pulses when the voltage of the latter exceeds the terminal voltage of the battery and in the nonconductive state during intervals between the charging periods; level detecting circuit means including means for detecting the terminal voltage of the battery in the intervals between the charging periods of the voltage pulses and means for comparing the detected terminal voltage with a reference voltage and providing an output to the control circuit means for shifting the switching means to the nonconductive state; and reference voltage control means.
