Description of drawings
The structural representation of a kind of charger system that Fig. 1 provides for the present embodiment.
Embodiment
The structural representation of a kind of charger system 1 that Fig. 1 provides for the present embodiment, as shown in Figure 1, the present embodiment provides a kind of charger system, comprise: charger 1, storage battery 2 and assistant starting module 3, assistant starting module 3 is used as the stand-by power supply of charger 1 when the storage battery 2 serious power shortage.Concrete:
Charger 1 comprises the first main circuit and the first control circuit that is connected, and during greater than the first predetermined voltage threshold, controls the first main circuit work at the control voltage of the input of first control circuit; Assistant starting module 3 comprises the second main circuit and the second control circuit that is connected, and during less than the second predetermined voltage threshold, controls the second main circuit work at the control voltage of the input of second control circuit.Charger 1 is similar with the operation principle of assistant starting module 3, whether the work of main circuit starts the control voltage of the input that is controlled by control circuit, and different to be charger 1 needed control voltage opposite with the required control voltage logic of assistant starting module 3, namely need high level to start such as the described charger 1 of the present embodiment, and assistant starting module 3 need low level to start.
The output that the input of the first main circuit is couple to electrical network 5, the first main circuits is connected to storage battery 2, is used for line voltage is converted into the supply power voltage of storage battery 2.The input of the first main circuit of charger 1 is couple to electrical network 5, is used for the voltage DC750V of electrical network 5 is converted to storage battery 2 and the required supply power voltage DC24V of other DC load.
The output that the input of the second main circuit is couple to electrical network 5, the second main circuits is connected to the input of first control circuit, is used for line voltage is converted into the control voltage of first control circuit.The second main circuit input, the output voltage of this assistant starting module 3 are consistent with input, the output voltage of the first main circuit of charger 1, i.e. DC750V input, and DC24V output, output voltage is as the control voltage of the first control circuit of charger 1.
The input of first control circuit is when being high level 12V for example in the present embodiment, during namely greater than the first predetermined voltage threshold, be 5V such as the first predetermined voltage threshold, the first main circuit work is carried out voltage transitions and is powered for storage battery 2 and other other DC load.But when storage battery 2 serious power shortage, the output voltage of its output is reduced to 2V, is 5V less than the first predetermined voltage threshold, and then the first main circuit can't be worked.
Because the second control circuit of assistant starting module 3 is opposite with the control voltage logic of the first control circuit of charger 1, when the input of second control circuit has the high level input, during namely greater than the second predetermined voltage threshold, for example during 5V, assistant starting module 3 is not worked.So because the input of second control circuit is connected to storage battery 2, when storage battery 2 also possesses certain electric weight, assistant starting module 3 is not worked, only has the voltage that causes its output when storage battery 2 serious power shortages during less than the second predetermined voltage threshold, concrete for example when the input of second control circuit be 0V or when unsettled, the second main circuit work of assistant starting module 3.

The charger system that the present embodiment provides, by assistant starting module 3 is set, the input of the second main circuit of assistant starting module 3 is used for being couple to electrical network 5, the input of the second control circuit of assistant starting module 3 links to each other with storage battery 2, and the output of the second main circuit links to each other with the input of first control circuit; Wherein, at the output voltage of storage battery 2 during less than the second predetermined voltage threshold, second control circuit work, starting the second main circuit, and then the second main circuit becomes electrical network 5 voltage transitions the control voltage of corresponding first control circuit.When storage battery 2 serious power shortage, assistant starting module 3 starts, and for charger 1 provides control voltage, thereby has solved the problem that charger 1 can't start because of storage battery 2 serious power shortages in the prior art.
The both positive and negative polarity of the input of the first main circuit is referring to the L+ that illustrates in the first main circuit among the figure, L-; The both positive and negative polarity of the output of the first main circuit is referring to the O+ that illustrates in the first main circuit among the figure, O-; The both positive and negative polarity of the input of first control circuit is respectively referring to the C+ that illustrates in the first control circuit among the figure, C-; The both positive and negative polarity of the input of the second main circuit is referring to the L+ that illustrates in the second main circuit among the figure, L-; The both positive and negative polarity of the output of the second main circuit is referring to the O+ that illustrates in the second main circuit among the figure, O-; The both positive and negative polarity of the input of second control circuit is respectively referring to the C+ that illustrates in the second control circuit among the figure, C-.
For further convenient operation person operation, preferred as technique scheme, also be connected with hand switch 4 between the second control circuit of assistant starting module 3 and the storage battery 2, when hand switch 4 is opened, second control circuit work, starting the second main circuit, and then the second main circuit converts line voltage to the control voltage of corresponding first control circuit.Concrete, hand switch 4 can be selected ground connection with the input of the second control circuit of assistant starting module 3, thereby provides control voltage for second control circuit.Thereby thereby force start assistant starting module 3 force start chargers 1 are system power supply.
Preferred as technique scheme, hand switch 4 is normally closed switch S1.When hand switch 4 is normally closed switch S1, then when 1 work of needs charger, disconnect normally closed switch S1, then the input current potential of assistant starting module 3 becomes 0V, and 3 work of assistant starting module provide control voltage for charger 1.
Because the input of the control circuit of charger 1 is connected to storage battery 2 and assistant starting module 3 simultaneously, for fear of problems such as assistant starting module 3 are short-circuited, preferred as technique scheme is between the positive pole of the positive pole of storage battery 2 and the input of first control circuit and be connected with the diode of forward conduction.The DC24V+ output of storage battery 2 is the positive pole of storage battery among Fig. 1, and the DC24V-output of storage battery 2 is the negative pole of storage battery.
