For the problems referred to above, for direct current cabinet charge power supply provides a kind of novel controller, in being integrally the problem that prior art needs to solve.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of direct current cabinet charge power supply controller, to charger export voltage carry out comprehensive judgement, took into account simultaneously, under voltage report to the police and defencive function.
For achieving the above object, the technical solution of the utility model is, a kind of direct current cabinet charge power supply controller, it is characterized in that: described controller is send into signal comparing unit after current feedback unit, voltage feedback unit gather the current feedback signal of charge power supply and voltage feedback signal respectively to judge, signal comparing unit connects overvoltage, undervoltage warning unit and optical relay output unit respectively.
Be provided with divider resistance in described current feedback unit and voltage feedback unit, dividing potential drop, shunting are carried out to the output voltage of charge power supply and electric current.
Optical relay output unit is connected by current-limiting resistance in described signal comparing unit.
A kind of direct current cabinet charge power supply controller, owing to adopting above-mentioned structure, the utility model has the advantage of: 1, carry out comprehensive judgement to the voltage that charger exports, took into account simultaneously, under voltage reports to the police and defencive function; 2, cost performance is high: circuit design is ingenious, and cost is low; 3, easy for installation: volume is little, line is few; 4, accuracy is high: adopt optical relay.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation of a kind of direct current cabinet charge power supply of the utility model controller;
Fig. 2 is the structural representation of a kind of direct current cabinet charge power supply of the utility model controller;
In FIG, 1, signal comparing unit; 2, current feedback unit; 3, voltage feedback unit; 4, overvoltage, undervoltage warning unit; 5, optical relay output unit.
Embodiment
Charge power supply controller is the key component of charger: it comprises DC control supply, given power supply, feedback sample voltage and current, amplifies the compositions such as comparison circuit.When AC supply voltage changes, charge power supply controller provides a precision voltage reference.Feedback sample voltage directly takes out from rectifier DC end, and compares amplification with reference voltage, controls the voltage of field effect transistor, goes the electric current controlling magnetic saturation reactor direct current winding to realize voltage stabilizing.When the load, current sampling compares with reference voltage same principle, finally realizes flow stabilizing function.
Specifically as shown in Figure 1, the utility model current feedback unit 2, voltage feedback unit 3 are sent into signal comparing unit 1 after gathering the current feedback signal of charge power supply and voltage feedback signal respectively and are judged, signal comparing unit 1 connects overvoltage, undervoltage warning unit 4 and optical relay output unit 5 respectively.
Be provided with divider resistance in current feedback unit 2 and voltage feedback unit 3, dividing potential drop, shunting are carried out to the output voltage of charge power supply and electric current.Optical relay output unit 5 is connected by current-limiting resistance in signal comparing unit 1.
After the utility model collects external bus signal, carry out the process of signal, when the fault such as overcurrent, overvoltage appears in signal, determine output alarm or relay output etc. by each signal characteristic.
As shown in Figure 2, exporting after DC bus-bar voltage when collecting charge power supply controller, after electric resistance partial pressure, entering comparator, after comparing with the set point of overvoltage or under voltage, determine whether overvoltage or under-voltage, then through current-limiting resistance, exported by optical relay.
The utility model can output overvoltage report to the police, undervoltage warning function.Omnibearing inspection charge power supply output voltage working condition, ensures the steady operation of direct current cabinet.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that technical solutions of the utility model are carried out; or directly apply to other occasion, all within protection range of the present utility model without improving.
