Abstract
The utility model provides a two-path charger and belongs to the technical field of charger. The utility model solves the problem that a charger in the prior art can only output a single voltage source. The two-path charger comprises a controller and a rectification filter circuit that can be connected to 220 V electric supply. A PWM control circuit and a DC / DC transformation circuit with an output port and connected with extraneous charging equipment are sequentially connected between the controller and the rectification filter circuit; and the controller can control the DC / DC transformation circuit to output two charging power source, 12 V /10 A and 24 V / 5A, through the PWM control circuit. The two-path charger has the advantage of capability to output two charging power source, 12 V /10 A and 24 V / 5A.
Description
Technical field
The utility model belongs to the charger technical field, relates to a kind of two-way charger.
Background technology
Charger is commonly referred to as a kind of equipment that alternating current is converted to low-voltage DC.Charger is of many uses in every field, and it is first-class particularly to be widely used in mobile phone, camera, automobile in sphere of life.Charger is to adopt power electronics semiconductor device, and voltage and the constant alternating current of fixed-frequency are transformed to galvanic a kind of static ac dc converter device.At present existing charger can only be exported a kind of current/voltage value separately usually, such as 12V/10A or 24V/5A, if will the equipment of these two kinds of current/voltages be charged respectively, just needs two chargers that can export these two kinds of current/voltages respectively.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, thereby has proposed a kind of two-way charger that can export 12V/10A and two kinds of electric currents of 24V/5A respectively that switches by self circuit.
The purpose of this utility model can realize by following technical proposal: a kind of two-way charger, comprise controller and the current rectifying and wave filtering circuit that can be connected with extraneous 220V electric main, it is characterized in that: also be connected with pwm control circuit between described controller and the current rectifying and wave filtering circuit in turn and have the DC/DC translation circuit that output port is connected with extraneous charging device, described controller can be controlled DC/DC translation circuit output 12V/10A or these two kinds of charge power supplies of 24V/5A by pwm control circuit.
In above-mentioned a kind of two-way charger; also be provided with the protective circuit that is connected with controller on the described two-way charger, described protective circuit comprises current foldback circuit, overvoltage crowbar, overpower protection circuit, reverse-connection protection circuit and thermal-shutdown circuit.
In above-mentioned a kind of two-way charger, described controller is single-chip microcomputer.
Compared with prior art, thereby carrying out the circuit conversion by pwm control circuit to the DC/DC translation circuit, this two-way charger can export 12V/10A or these two kinds of voltage sources of 24V/5A, thereby such charger can be respectively to the equipment charge of 12V/10A or 24V/5A, and do not need to prepare to export respectively two chargers of these two kinds of voltages, make the charger applicable scope more extensive.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this two-way charger comprises single-chip microcomputer and the current rectifying and wave filtering circuit that can be connected with extraneous 220V electric main, also be connected with pwm control circuit between single-chip microcomputer and the current rectifying and wave filtering circuit in turn and have the DC/DC translation circuit that output port is connected with extraneous charging device, the monolithic function is by pwm control circuit control DC/DC translation circuit output 12V/10A or these two kinds of charge power supplies of 24V/5A.
Also be provided with the protective circuit that is connected with single-chip microcomputer on the two-way charger, described protective circuit comprises current foldback circuit, overvoltage crowbar, overpower protection circuit, reverse-connection protection circuit and thermal-shutdown circuit.
During use, the power input that will be connected with current rectifying and wave filtering circuit is linked on the mains supply, and the output port of power source that will be connected with the DC/DC translation circuit is linked on the equipment of needs charging, and equipment can be the charge power supply requirement of 12V, also can be 24V.At charger switching push button is installed, switching push button is connected with single-chip microcomputer, and when the operation switching push button switched to that side of 12V, single-chip microcomputer transmitted control signal to pwm control circuit, pwm control circuit control DC/DC translation circuit output 12V voltage source; Otherwise when switching push button switched to that side of 24V, single-chip microcomputer transmitted control signal to pwm control circuit, pwm control circuit control DC/DC translation circuit output 24V voltage source.The charging voltage of output is controlled by single-chip microcomputer, and charge mode has deeply and fills, fills soon and the floating charge stage, and each stage has different indicator lights to show.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
