The invention discloses a pulse separating circuit for a motorcycle igniter and relates to a motorcycle ignition circuit. The pulse separating circuit mainly comprises a positive pulse processing circuit, a negative pulse processing circuit, two pulse comparison amplifiers, two Schmidt triggers and a discharge circuit. In the pulse separating circuit for the motorcycle igniter, the pulse separating circuit and a motorcycle automatic angle-advancing control circuit are integrated into the same chip, so that the problems of too many peripheral elements, inconvenient debugging, high cost and thelike in the universal ignition circuit are solved. Furthermore, in the circuit, pulse separation is realized by adopting the two-stage amplifiers so that the minimum rotary speed (less than 50 r / min)of motorcycle ignition is greatly reduced.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a motorcycle igniter. Background technique [0002] The igniter is a key component in the motorcycle, which plays an important role in the normal running of the motorcycle and the personal safety of the driver. The pulse separation circuit is a circuit that separates the positive and negative trigger pulses of the igniter into two negative pulses. The separated pulse signals can be used by the motorcycle automatic timing control chip to realize the automatic timing ignition of the motorcycle. The traditional pulse separation circuit for motorcycles uses a triode for pulse separation such as figure 1 shown. However, its pulse separation circuit is realized by separation components, which makes the application circuit of the motorcycle igniter have too many peripheral components, which is inconvenient to debug and has a high cost. Moreover, since the pulse separation is perfo...
