Trigger formula transformer provided by the invention, two power input e
1, two output u
2, two trigger ends, two reset terminals.There is parameter coupling in the input of power supply and outlet chamber, the inductance of output winding forms non-linear output loop together with electric capacity.
In nonlinear loop, there is two or more amplitude stability states.Low frequency nonlinear loop, is mainly various ferro resonances loops, and at two stable oscillation stationary vibration chapter platforms that close on, output voltage loop amplitude differs 3-4 doubly, i.e. degree of isolation between conducting and blocking is little more a lot of than trigger formula transformer.In trigger formula transformer, in order to improve the isolation between conducting and locking, output winding W
2 /and W
2 //, and the iron core column at these two winding places is all symmetrical.Be added to winding W
2 /and W
2 //on voltage magnitude equate, single spin-echo.Frequency is the supply voltage u of ω
1be added to input winding W1 upper, the magnetic flux that it produces is equally distributed in the iron core column at this winding place, due to two iron core column full symmetrics on both sides, and output winding W
2 /and W
2 //reversal connection, the output voltage u under blocking
1close to zero.Therefore,, in trigger formula transformer, between input and output circuit, do not have transformer coupled.If the magnetization curve of iron core is linear, can there is blocking, when magnetization curve exists when non-linear, in trigger formula transformer by the stable vibration of excitation place, input voltage u
1frequency the most effective while being ω.
In fact, if current i

1time, in output loop, the amplitude of signal is enough large, the inductance L of output loop
2not only and i
1relevant, and and i
2relevant.In this case, whole device is as a Nonlinear Oscillation System.In order to realize frequency of oscillation ω in this Nonlinear Oscillation System, necessary and sufficient condition is the resonance frequency omega that makes loop
0close to supply frequency ω, inductance L
2relative variation should be enough to the decay in compensation circuit.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
