Abstract
The charger comprises a circuit which includes a reactance before or after a transformer and includes a rectifier, a pull-off and/or an equalizer, formed of at least one diode/rectifier assembly, being provided between both branches of the circuit; the pull-off circuit may be substituted by a switch-off circuit to cut off the charging when the accumulator is carged. The charge is produced by voltage drop by voltage differential maintaining the amperage.
Claims21
A charger for electrical accumulators, comprising:
- input terminals for receiving an input signal;
- output terminals for producing an output signal;
- a transformer connected to the input terminals for producing an alternating current output signal at a voltage greater than a rated voltage of said accumulator to be charged, said transformer producing said alternating current output signal in response to the input signal;
- rectifier means for rectifying the alternating current output signal from said transformer to produce a direct current output signal and for supplying said direct current output signal to said output terminals;
- circuit means for regulating said output signal of said charger by producing a voltage drop of said input signal while ensuring that a substantially constant amperage is produced by said charger, said circuit means including a reactance connected between said transformer and said input terminals;
- and
- overcharging prevention circuit means for preventing overcharging of said accumulator after the accumulator has been charged, said overcharging prevention circuit means being connected in parallel with said rectifier means.
