Abstract
The invention relates to a functional thyristor phase-shifting trigger, which comprises a self-generating power circuit, a functional circuit and a synchronous shift circuitThe phase pulse circuit and transistor AC switch are composed of DC power supply, DC power supply and DC power supply1，T2The power supply can work by electricity, and the self-control function is added under the condition of not additionally applying power supply voltage.
Description
The present invention relates to electric and electronic technical field.
Prior art of the present invention has two kinds: a kind of is trigger tube (as bidirectional trigger diode Diac or silicon bidirection switch SBS) phase-shift trigger circuit (" controllable silicon application technology ", Chinese science technical literature publishing house Chongqing branch." novel electric power Physics of Semiconductor Devices and application ", China Machine Press), deficiency is to have only single phase shift function, is difficult for additional other automatic control functions.Advantage is to be connected into one-port with thyristor (Triac), does not need to add in addition power supply voltage, can two line traffic controls to electrical load.Another kind is discrete component phase-shift circuit or integrated phase-shift trigger circuit (" KC series silicon controlled toggle ", Shanghai Electric Appliances Science Inst of electromechanics portion product .), deficiency be can not lean on list connect with thyristor electric work, must add power supply voltage in addition, make on the whole and will use three wires at least.These domestic architectures in a large number having buried electric wire add a wire, not only waste, and trouble, and also it is attractive in appearance and can not accept to destroy original wiring.
Problem in view of above-mentioned prior art existence, the present invention's purpose is to propose a kind of new technical scheme, realization can need not to add in addition power supply voltage as the trigger tube circuit, can increase multiple automatic control function again simultaneously (as timing, loop cycle, or additional electron watch core IC or intelligent program-controlled, circuit such as remote control).
Accompanying drawing is the present invention's a schematic diagram.
The design of finishing above-mentioned technology is: a kind of functional thyristor phaseshift trigger, and by the authigenic power supply circuit U, functional circuit F, simultaneous phase-shifting impulse circuit P and transistor alternating-current switch S form. Its advantage is that it goes up to get electric work by nearly gate pole T1 and the far away from home utmost point T2 that is directly parallel in IGCT. Existing The phase shift Trigger Function, can increase simultaneously multiple automatic control function again, more need not to add in addition power supply voltage, it is characterized in that: in the above-mentioned phase shift trigger, the other end of the capacitance-resistance parallel impedance Z that connects with an end of the rectifier bridge AC of authigenic power supply, the other end of the resistance R 1 that connects with the input of zero cross signal detecting circuit W, the other end of the resistance R 2 that connects with transistor alternating-current switch S, the three is connected on the T2 of IGCT altogether. Functional circuit is connected across on the positive and negative terminal of authigenic power supply rectifier bridge DC side. Simultaneous phase-shifting impulse circuit P detects zero cross signal by zero cross signal detecting circuit W, and is anti-phase and be converted to current source output, to the capacitor C constant-current charge, form linear rising sawtooth waveforms, produce phase-shift pulse output through comparator A, driving transistors alternating-current switch S output triggers IGCT. Above-mentioned zero cross signal detecting circuit W is interconnected as output with two transistorized colelctor electrodes, and the base stage of a pipe connects as input with the emitter stage of another pipe, and the remaining electrode of two pipes then connects with the negative terminal of authigenic power supply DC side. Above-mentioned transistor alternating-current switch S is formed by transistor and rectifier bridge connection. The anode of rectifier bridge DC side connects with colelctor electrode, and negative terminal then connects with emitter stage. One end of this rectifier bridge AC is connected to the gate pole G of IGCT, the other end of AC and resistance R 2 and bi-directional voltage stabilizing pipe D(such as transistorized Vceo are enough, voltage-stabiliser tube can be economized) an end connect, the other end of the other end of bi-directional voltage stabilizing pipe and authigenic power supply rectifier bridge AC all connects altogether with the T1 of IGCT. Therefore as three outer contacts of functional form phase-shift trigger circuit of the present invention, all receive on the electrode of IGCT (T1, T2, G), can be connected in series work with AC load, do not need to connect again power line.
