The invention discloses a timing ending type pulse controlled floating charger, and belongs to the field of electronic technique. The timing ending type pulse controlled floating charger consists of atrickle resistor, a constant current unit, a charge unit, an interface unit, a pulse oscillating unit, a timing ending unit, a voice control unit, a load unit and a process indicating unit; the constant current unit is used for providing constant current for the charge unit, and thus constant current charging is realized; however, under the control of the interface unit, a charging and charging-stop pulse charging mode of the charging unit and the pulse oscillating unit is formed, and the charging time is longer than the charging-stop time, so that scientific charging for a charged battery isrealized, and the rejection rate is reduced; a timing ending type is adopted, a timer in the timing ending unit is low in static power consumption and wide in operating voltage range; after timing isended, the interface unit and the voice control unit are turned on, voice reminding is emitted while the charge unit is turned off, and simultaneously, the trickle resistor is used for providing sustaining trickle for the charged battery. The timing ending type pulse controlled floating charger is simple in circuit and easy to produce and debug, and is extremely applicable for microenterprise production.

The invention relates to a low-carbon silicon controlled rectifier type environmentally friendly charger and belongs to the electronic technical field. The low-carbon silicon controlled rectifier type environmentally friendly charger is composed of a constant-current power source, a charging unit, a pulse unit, a process indication unit, a timing termination unit, a selection unit, a voltage limiting termination unit, a load unit and a trickle resistor. The charging unit is controlled by the oscillation of the pulse unit to form a pulse form; and the power source of the charging unit is provided by the constant-current power source, and constant-current charging can be realized. The timing termination unit and the voltage limiting termination unit enable two termination modes; when voltage limiting termination is selected, timing termination does not act; as for a battery having a requirement for charging time, the timing termination is selected, and the voltage limiting termination is not enabled; and therefore, selection is flexible and convenient. According to the charging unit of the charger of the invention, two innovative silicon controlled rectifiers are in special parallel connection; under normal circumstances, only one silicon controlled rectifier works, and the other silicon controlled rectifier is adopted as a backup silicon controlled rectifier; and when one of the silicon controlled rectifiers is damaged, the other silicon controlled rectifier actively substitutes the damaged silicon controlled rectifier; and therefore, the service life of the charger can be greatly prolonged.
