Abstract
The utility model provides a driving control circuit of an inductance ballast. The driving control circuit is formed by connection of a protection circuit, various switch tubes and a circuit control chip, wherein four pins of the circuit control chip are connected with the switch tubes, the protection circuit is connected with a circuit control chip, and the switch tubes are connected with the protection circuit after being connected with one another. With the driving control circuit, a better stability of the inductance ballast is achieved.
Description
Technical field
The utility model relates to a kind of Drive and Control Circuit, particularly a kind of Drive and Control Circuit of Inductive ballast.
Background technology
In prior art, as patent ZL200610113078.X discloses a kind of electric ballast, comprise current rectifying and wave filtering circuit, for common alternating current is carried out to rectification, filtering; Also comprise high-voltage trigger, be used to load that the high-voltage trigger signal while starting is provided, described electric ballast also comprises switching inverter and control unit; Described switching inverter receives the direct current of current rectifying and wave filtering circuit output, and the direct current receiving is converted to the voltage and current that the electrical characteristic with load matches, and during direct current is transformed to, low-frequency square-wave signal, for driving the operation of load (R0); Described control unit is for controlling the operation of electric ballast.Existing electric ballast stability is bad.
Utility model content
The utility model proposes and a kind ofly can make the better Drive and Control Circuit of Inductive ballast stability.
The technical solution of the utility model is achieved in that
A kind of Drive and Control Circuit of Inductive ballast; by protective circuit, various switching tube and circuit control chip, connected to form; four pins of described circuit control chip are connected with switching tube respectively; protective circuit is connected with circuit control chip; switching tube connects each other, then is connected with protective circuit.
Further, described protective circuit is connected with filter capacitor.
Further, described protective circuit is fuse.
Further, described fuse is fuse wire.
Useful benefit of the present utility model: because four pins of described circuit control chip are connected with switching tube respectively; protective circuit is connected with circuit control chip; switching tube connects each other; be connected with protective circuit again; so opening switch pipe; conducting, realizes and drives Inductive ballast, makes Inductive ballast stability better.Because described protective circuit is connected with filter capacitor, so there is filter action.
