Abstract
The utility model provides a circuit device of realizing an adjustable current. The circuit device of realizing the adjustable current comprises a power supply unit used for supplying power to all power units of the circuit device, and also comprises a circuit module of realizing the adjustable current. The circuit module comprises the following circuit units: a rectification circuit used for adjusting an externally added AC into a DC, and a comparator circuit used for comparing an inputted AC with a preset current, when the inputted AC is less than a preset value, inputting the AC to a first circuit unit to charge, and when the inputted AC is greater than preset value, inputting the AC to a second circuit unit to charge. The circuit device of realizing the adjustable current of the utility model has an optional charging mode, different currents can charge different component charging circuits.
Description
Technical field
The utility model relates to a kind of circuit devcie of realizing adjustable current.
Background technology
" charging " is the process that the equipment such as accumulators replenishes electric weight, and its principle is to allow direct current pass through from the opposite direction of discharging, so that active material restitution in storage battery.
Storage battery is accepted electric energy from external circuit, is converted into the course of work of the chemical energy of battery.Storage battery, recovers by charging after discharge consumes at its energy, can again discharge again, consists of to charge and discharge circulation.General with direct current (also useful asymmetrical alternating current electric current or pulse current) charging.Under different situations, adopt the combined charging of different charging methods such as constant current charge, constant voltage charging, floating charge, trickle charge, boost charge or these methods etc.But existingly realize that the circuit devcie of adjustable current is single by charging modes, can not realize that different electric currents realizes the charging of different components and parts charging circuits.
The utility model content
The utility model proposes a kind of circuit devcie of realizing adjustable current, solved charging modes single, can not realize that different electric currents realizes the problem of the charging of different components and parts charging circuits.
The technical solution of the utility model is achieved in that
The utility model discloses a kind of circuit devcie of realizing adjustable current, comprise power supply unit, be used for all power units of circuit devcie are powered, also comprise the circuit module of realizing adjustable current, described circuit module comprises following circuit unit:
Rectification circuit is used for the alternating current that adds is adjusted to direct current;
Comparator circuit, be used for will input alternating current compare with default electric current, when lower than preset value, input to the first circuit unit and charge, when higher than preset value, be input to the second circuit unit and charge.
In the circuit devcie of realizing adjustable current described in the utility model, described the first circuit unit comprises the charging circuit of mobile phone.
In the circuit devcie of realizing adjustable current described in the utility model, described second circuit unit comprises the charging circuit of panel computer.
Implement a kind of circuit devcie of realizing adjustable current of the present utility model, have following useful technique effect:
Charging modes has alternative, and different electric currents can be realized the charging of different components and parts.
