The utility model for achieving the above object, the technological scheme of taking is: a kind of Drive and Control Circuit of composite automobile electronic igniting controllor, it is characterized in that: comprise stabilized power supply U1, signal deteching circuit U2, current-limiting circuit U3, high-voltage high-power transistor Q1, sample resistance R1, the end of the termination signal deteching circuit U2 of described stabilized power supply U1, the output terminal of the output termination current-limiting circuit U3 of signal deteching circuit U2 and the B utmost point of high-voltage high-power transistor Q1, the E utmost point of high-voltage high-power transistor Q1 connects the input end of current-limiting circuit U3 and the end of sample resistance R1, the other end ground connection of sample resistance R1.
The beneficial effects of the utility model: this Drive and Control Circuit of lighting a fire, by some simple common circuit, realized the function that external chip degree circuit is finished, the technology barriers of external producer have effectively been got around, can reduce enterprise's cost of production greatly, will be for national auto parts and components export base increase new product, the development of driving automobile electronic component has obtained good income.
Description of drawings
Fig. 1 is circuit diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of Drive and Control Circuit of composite automobile electronic igniting controllor, comprise stabilized power supply U1, signal deteching circuit U2, current-limiting circuit U3, high-voltage high-power transistor Q1, sample resistance R1,1 pin of spark coil T1 connects the end of automobile power source 14V and stabilized power supply U1, the end of another termination signal deteching circuit U2 of stabilized power supply U1, the input end of signal deteching circuit U2 meets signal input SI respectively, signal ground VSS, the output terminal of the output termination current-limiting circuit U3 of signal deteching circuit U2 and the B utmost point of high-voltage high-power transistor Q1, the E utmost point of high-voltage high-power transistor Q1 connects the input end of current-limiting circuit U3, the end of sample resistance R1, the other end ground connection of sample resistance R1,2 pin of the C polar contact fire coil T1 of high-voltage high-power transistor Q1, the 4 pin ground connection of spark coil T1,3 pin of spark coil T1 connect automobile spark plug.
In the utility model design, adopt the IGBT high-voltage high-power transistor Q1 of a new generation, it is a kind of voltage-type control means, its needed driving current and driving power are very little, its input resistance is very big, switching loss is little, can be directly and the analog or digital function block join and must not add any additional interface circuit.High-voltage high-power transistor Q1 is as switching device, and the saturation conduction of main research high-voltage high-power transistor Q1 and by two states in drive circuit makes it open rising edge and turn-offs all steeper of trailing edge.High-voltage high-power transistor Q1 is the same with other power electronic devices, and its application-dependent is in circuit condition and switch environment.Therefore in the design process of product, the driving of high-voltage high-power transistor Q1 and protective circuit are difficult point and the emphasis of circuit design, are the key links of whole device operation.
The power supply of Automobile Igniting Control device is generally car accumulator; its voltage functuation is bigger, uses suitable voltage-stabilizing device and capacitance resistance ware, and too high voltage is stabilized in the 7.5V; effectively protection controller internal components has prevented the fluctuation of the initial firing current of coil simultaneously.
The input fire signal, in automobilism, fire signal can be interfered unavoidably, becomes imperfect; Use the signal of signal deteching circuit U2 to carry out shaping, suitable voltage threshold is set, can effectively exclude the interference signal, prevent the coil mis-ignition; Simultaneously, the output of signal deteching circuit U2 will be a complete signal waveform, can effectively drive high-voltage high-power transistor.
