Abstract
Broad-band electronic pulse transformer is a kind of pulse transformer of being made up of high-frequency generator 1, isolating transformer 2, forward wave detector 3 and reverse wave detector 4.It is except having the general characteristics that the pulse transformer isolation performance is good, power output is big, and its biggest advantage is not only can pass on high-frequency signal but also can transmit low frequency or direct current signal.Therefore, it is particularly suitable for doing pulse transformer or isolating transformer use in the electric installation of a few thing under low frequency or direct current situation.
Description
The present invention is a kind of pulse transformer.
Existing pulse transformer has the advantage that isolation performance is good, power output is big and impedance is easily mated.In some electric installations, people often use it as pulse transformer or isolating transformer.But the disadvantage that this class pulse transformer exists is a narrow bandwidth.It just can not meet the demands when therefore, the signal that it is provided as if some circuit requirement in the electric installation was low frequency or direct current.
The purpose of this invention is to provide a kind of high-frequency pulse signal of can exporting and to export the broad-band electronic pulse transformer of direct current signal again to satisfy the needs of some electric installations.
The present invention is finished by following scheme.
What Fig. 1 provided is functional-block diagram of the present invention.
With reference to Fig. 1: this broad-band electronic pulse transformer has high-frequency generator 1, isolating transformer 2, forward wave detector 3 and reverse wave detector 4.The output that it is characterized in that said high-frequency generator 1 links to each other with the input of isolating transformer 2; When having given signal U, the input of high-frequency generator 1 provides high-frequency oscillation signal to isolating transformer 2 by high-frequency generator 1.The output of said isolating transformer 2 links to each other with the input of forward wave detector 3 with reverse wave detector 4; When isolating transformer 2 is exported positive half wave under the control of high-frequency generator 1 during by the negative half-wave of forward wave detector 3 output pulse signals, output by reverse wave detector 4 output pulse signals.Said forward wave detector 3 and reverse wave detector 4 take mode in parallel to export; Like this, this broad-band electronic pulse transformer just can provide one by many burst pulses synthetic and synthetic after its frequency of waveform and the same signal of telecommunication of given signal U.
This broad-band electronic pulse transformer provided by the invention U export during for high-frequency pulse signal be one by synthetic its frequency signal of telecommunication identical of a series of burst pulses with U, at U is under the situation of direct current, what export is a dc signal that is synthesized by a series of burst pulses, as seen, suitable wide of its frequency band, not only overcome the shortcoming of existing pulse transformer narrow bandwidth, and it has also kept the advantage that original pulse transformer isolation performance is good and power output is big.
Fig. 2 is an example implementing principle of the invention block diagram.
The frequency range of above its signal of telecommunication of being exported of example is 0 to 600 * 10
3About He Zhi.
Given signal U can be provided also and can be provided by some other devices such as computers by oscillator.The frequency of given signal U can change at any time, and at this moment, its frequency of the signal of telecommunication that this broad-band electronic pulse transformer is exported also will be along with the change of the frequency of given signal U and changed (but the frequency of burst pulse is constant).
This broad-band electronic pulse transformer is particularly suitable for doing in the electric installation of a few thing under low frequency or direct current situation pulse transformer or isolating transformer uses.
