Description

A kind of pulse generator

The invention provides a kind of dynamic pulse generator; This pulse generator integrates pulse generator, pulsqe distributor, and its basic circuit that produces pulse does not have oscillating circuit and frequency dividing circuit, therefore can claim that it is a mechanical type Pulse-trigger control device yet.

At present, a large amount of comparatively complicated electronic impulsers that use, be subjected to all multifactor impacts of external powers such as line voltage and waveform distortion of the power supply network very big, the difficult control of the precision of output pulse, and the influence that the circuit that produces pulse is subject to disturb, in the automatic control technology field, the signal element of numeral----simulation hybrid control system (as tachogenerator etc.), because there are such-and-such shortcoming in its agent structure and adjunct circuit structure, make and forms the reliability and the precision of system and form the degree of freedom reduction of system very big by them.In the pulse technique field, though the electronic impulse technical development is very fast, in order multiple row be associated uniformly-spaced or the clock-pulse generator of the frequency conversion of unequal interval, its structure and structural principle are still very complicated.And general electronic impulser is directly exported the power of pulse can not be too big.

The objective of the invention is to try hard to overcome to a certain extent deficiency of the prior art, provide a kind of pass through commutator brush, commutator, collector ring and brush thereof of former moving element control of utilizing that direct current is converted to the device of pulse, this device can be exported the large power, electrically magnetic field impulse by electromagnetic conversion element; Also can be by corresponding pulse transformer output start pulse signal.
