The utility model relates to a controlled silicon AC regulator which is suitable for a single-phase AC circuit whose voltage is between 380V to 220V. A circuit of the controlled silicon AC regulator is reversely connected with two thyristors in parallel, a bidirectional thyristor is connected between two control electrodes of the two thyristors, and a control board of the bidirectional thyristor is serially connected with a potentiometer and a resistor. The controlled silicon AC regulator can freely regulate the voltage and switch on and off within the rated voltage, and the controlled silicon AC regulator is suitable for the control and the adjustment of various single-phase electrical equipment.
Description
The utility model is a kind of SCR AC adjuster, is applicable to 380V～220V single phase alternating current circuit, can be in rated voltage pressure regulation and the multifunctional adjustment device that cut-offs arbitrarily, be applicable to the control and the adjustment of various single phase circuit equipment.
At present, all SCR control circuit all be unable to do without the triggering signal control circuit, with the simplest capacitance-resistance phase shift bridge-type circuits for triggering, the self-maintained circuit of unijunction transistor, spike produces circuit, sawtooth wave generating circuits etc. all be unable to do without the secondary low-voltage loop, minimum tens kinds or tens kinds of Resistor-Capacitor Unit, hundreds of, complex circuit, investment is big, the cost height, general personnel are difficult to grasp, and line fault is many, the maintenance trouble, influence is produced, and causes the inconvenience of use.
The purpose of this utility model provides a kind of SCR AC adjuster that triggering signal need not be set, this adjuster is by two common controllable silicons and a bidirectional triode thyristor, a potentiometer is formed, its operation principle is to utilize the drain voltage of two control of two silicon controlleds utmost point, the direction of leakage current and alternating current changes, triggering and conducting utilizes bidirectional triode thyristor and potentiometer to control its conducting angle more mutually, thereby reaches the purpose of adjusting voltage control circuit equipment.
The utility model is realized in the following way: two controllable silicons of inverse parallel in circuit, in the middle of two controls of these two antiparallel silicon controlleds extremely, seal in a bidirectional triode thyristor, potentiometer of serial connection and resistance in bidirectional triode thyristor control extremely, adjust the resistance of potentiometer, just can change the angle of bidirectional triode thyristor conducting, the angle of controllable silicon conducting has also just been controlled in the variation of bidirectional triode thyristor conducting angle, has realized the function of modulation circuit.
Below in conjunction with accompanying drawing the utility model is described in detail
Fig. 1 is a circuit working schematic diagram of the present utility model
The utility model SCR AC controller is by the common controllable silicon 1,2 of control conducting, and bidirectional triode thyristor 3 changes the potentiometer 4 of bidirectional triode thyristor conducting angle, fixed resistance 5, and resistance-capacitance protection resistance 6 and electric capacity 7 are formed.The input V of the positive pole of controllable silicon 1 and phase-connecting wire after the negative pole of controllable silicon 2 is in parallel
SThe output V of the back anodal in parallel phase-connecting wire of the negative pole of controllable silicon 1 and controllable silicon 2
TTwo ends, resistance 6 and electric capacity 7 series connection back respectively with the input V of phase line
SWith output V
TConnect; The two poles of the earth of bidirectional triode thyristor 3 are connected with the control utmost point of controllable silicon 1 and controllable silicon 2 respectively; Potentiometer 4 is connected with the control utmost point of bidirectional triode thyristor 3 with fixed resistance 5 series connection backs one end, and the control utmost point of the other end and controllable silicon 1 and a utmost point of bidirectional triode thyristor 3 are in parallel; The zero line of phase line is from input V
SDirectly be linked to output V
T
The course of work of the present utility model: with the high-power alternating light of control arenas is example, input V
SInsert corresponding power supply (220V or 380V), output V
TAccess will become the high-power alternating light of light, when needs conversion light, potentiometer 4 can be adjusted counterclockwise, because the resistance of potentiometer 4 becomes, and the conducting angle of bidirectional triode thyristor 3 is diminished, bidirectional triode thyristor 3 has been controlled controllable silicon 1 and controllable silicon 2 again simultaneously, because be idiostatic, the conducting angle of controllable silicon 1 and controllable silicon 2 also diminishes gradually, and the voltage and current that passes through reduces, output V
TVoltage on average reduces, thereby light dies down, and continues contrary timing again, just can close 7 control of fixed resistance 6 and electric capacity protective effect, 5 metering functions of fixed resistance; Otherwise when needing to use high light, levelling clockwise reaches the brightness of control light, and as the control desk fan, ceiling fan etc. are adjusted to fast clockwise, are adjusted at a slow speed counterclockwise.
The utility model is applicable to various illumination light modulations; Equipment temperature adjustments such as electric iron, electric iron, electric rice cooker, electric furnace, roaster; Stepless speed regulations such as all kinds of electric fans, ceiling fan, small-sized single-phase motor; To charger, the small electrical welding machine carries out pressure regulation and transfers electric current.And it is simple in structure, cheap, of many uses, easy to use.Electric component can be fixed in the circuit board, also can directly connect with lead, can be assembled into the socket of different purposes, also can form a complete production network with other electric product.Power savings is obvious.
