ABSTRACT:
A battery charger comprises a rectifier connected to a source of alternating voltage for generating a rectified sinusoidal halfwave voltage and a thyristor connected in a first circuit between the rectifier and a rechargeable battery for applying the sinusoidal halfwave voltage thereto. An RC triggering network is provided in a second circuit between the battery and the gate of the thyristor for triggering the same into conduction to apply the sinusoidal voltage to the battery when the instantaneous value of the voltage is higher than the voltage of the battery. A temperature responsive switch is provided for disconnecting the second circuit when the battery is heated to a temperature higher than a predetermined value. Further provided is a transistor responsive to the temperature responsive switch for establishing a short-circuit path to the gate of the thyristor.
