Abstract
The invention discloses a kind of design of electronic circuits and application new departure.Its core content is applied in the constant-current circuit of automotive ignition module by a common three-terminal voltage regulator part, mixes several passive devices on a small quantity and replace traditional ignition module constant-current circuit, makes circuit more simple, reliable; Working together, constant current performance is more stable, temperature characteristic is better.The program can be used in the ignition module constant-current circuit of various ways, also can adapt to the ignition module circuit that output stage adopts different qualities power tube (Darlington transistor or IGBT).
Description
Technical field
The present invention relates to a kind of design of electronic circuits.
Background technique
Traditional ignition module constant-current control circuit common are two kinds of forms: (1) active module embedded therein constant-current circuit, generally carries out controlling (see Fig. 1) with comparator; (2) passive module constant-current circuit, generally carries out controlling (see Fig. 2) with triode.
The constant-current control circuit part of above two kinds of forms is shown in contained part in figure centre circle.Control principle is all substantially identical.When input end has triggering high level signal, the conducting of output switch power tube, On current produces a sampling voltage on current sampling resistor RL, when this voltage reaches setting value, the working state of the core parts (Q1 in IC1, Fig. 2 in Fig. 1) of current constant control part starts to change, on state is become from original cut-off, the driving voltage being added to switching power tube base stage or controlling pole is declined, thus switch power Tube current is declined, thus reach the effect of constant current.
But Shortcomings part all distinguished by the conventional module constant-current circuit shown in Fig. 1,2, Fig. 1 circuit is complicated, and add ons is many, and debugging also bothers.And can only could adopt in active module embedded therein circuit, cannot adopt in passive module.Fig. 2 number of circuit elements is many, poor work stability, and temperature characteristic is poor, although be provided with temperature compensating element, but still does not reach the effect of desirable constant current.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provides a kind of constant-current control circuit that all can use in active and passive module, and simply, component number is few, working stability, good temp characteristic for circuit arrangement.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of automotive ignition module constant-current control circuit, it is characterized in that, described constant-current control circuit 3 is made up of three ends voltage-stabiliser tube able to programme, current sampling resistor RL and programming resistors R1, a R2: the negative electrode of three ends voltage-stabiliser tube able to programme is connected to switching power tube base stage (control pole), and the reference edge of three ends voltage-stabiliser tube able to programme connects on the dividing point of programming resistors R1, R2 composition; Resistance R1 the other end connecting valve power tube base stage, the resistance R2 the other end is connected on current sampling resistor RL; The anode of three ends voltage-stabiliser tube able to programme connects common port (power cathode).
Adopt technique scheme, by a common three ends voltage-stabiliser tube device application able to programme in the constant-current circuit of automotive ignition module, mix several passive devices on a small quantity and replace traditional ignition module constant-current circuit, make circuit more simple, reliable; Working together, constant current performance is more stable, temperature characteristic is better.The program can be used in the ignition module constant-current circuit of various ways, also can adapt to the ignition module circuit that output stage adopts different qualities power tube (Darlington transistor or IGBT).
Beneficial effect of the present invention is, circuit arrangement simplicity of design, and component number few (4 elements), working stability, good temp characteristic, carries out temperature correction in whole operating temperature range.Reach desirable constant current effect.All can use in active and passive module, can be widely used in various ignition module as constant-current control unit.
