Abstract
Technical field of the present invention belongs to electrotechnics rectifier part, but purpose is the rectification that realizes the pressure regulation of alternating current.Principle is as the resistance size of figure by regulator potentiometer, flow through the phase difference of the electric current of base stage when flowing through the electric current of short circuit place and transistor collector and emitter when changing transistor collector and emitter, come the voltage height on the regulating load RL not by short circuit by short circuit.
Description
Technical field that the present invention belongs to.
Belong to electrotechnics rectification circuit part.
So far as I know this aspect prior art is to adopt diode rectification or silicon controlled rectifier.
But the purpose of this invention is the rectification that realizes the high efficiency pressure regulation of alternating current.
The content of invention:
As Fig. 1 (the K switch part is only drawn for ease of explanation among the figure), I
1During for switch closure, also be transistor collector and emitter during, flow through the electric current of K switch by short circuit.And I
bThen flow through the electric current of transistor base b during not by short circuit, I for transistor emitter and collector electrode
2=β * I
b(β is the triode multiplication factor), I
2Be transistor collector and emitter not by short circuit, and base current is I
bThe time allow to flow through the maximum current of collector electrode.We come as can be seen from Fig. 2, I
1And I
2Intersection area (promptly drawing oblique line part area) flow through load R when disconnecting for K switch
LElectric current.
Obviously, when K switch disconnected, we only needed the resistance of regulator potentiometer W, just can regulate the electric current I that flows through base stage b in Fig. 1
bPhase place because I
2And I
bTherefore same-phase just can regulate electric current I with this
1And I
2Phase difference.Make I among Fig. 2
1And I
2The intersection area (promptly flow through load R
LElectric current) change because voltage equals resistance and takes advantage of electric current, therefore that is to say and can come regulating load R by the resistance size of regulator potentiometer W
LOn size of current.
Claims (2)
1, the invention belongs to electrotechnics rectifier part, that works regulates the voltage height of exporting after the rectification as silicon controlled rectifier.
Flow through the phase difference of the electric current of base stage when 2, feature of the present invention is emitter by regulating triode and the current collection collection electric current that flows through short circuit place during by short circuit with transistor collector and emitter not by short circuit, control the output voltage rectification circuit just of rectification circuit.
