Description of drawings
Accompanying drawing is the utility model circuit structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises first resistance R 1, slide rheostat W, first capacitor C 1, bidirectional thyristor KS and neon tube TD; Two ends after first resistance R 1, slide rheostat W and 1 series connection of first capacitor C are parallelly connected with two main electrodes of bidirectional thyristor KS; The end of neon tube TD is connected with the sliding end of slide rheostat W; The other end of neon tube TD is connected with the control utmost point of bidirectional thyristor KS; Be connected with an end of ac power supply after the main electrode of bidirectional thyristor TD connects fan electromotor M, another main electrode of bidirectional thyristor KS is connected with the other end of said alternating voltage.
Shown in accompanying drawing: the utility model comprises that also two ends and two main electrodes of bidirectional thyristor KS after second resistance R 2 and second capacitor C, 2, the second resistance R 2 and 2 series connection of second capacitor C are connected in parallel.
Shown in accompanying drawing: the utility model also comprises the 3rd resistance R 3, and said the 3rd resistance R 3 is connected in series between said neon tube TD and the said bidirectional thyristor KS.
Shown in accompanying drawing: electric fan stepless time adjustment circuit; Be to utilize bidirectional thyristor KS on-line operation in ac power supply; Regulating second resistance R 2 is the angle of flow of may command bidirectional thyristor at positive and negative two half cycles of power supply, reaches the purpose that changes fan motor M rotating speed with the input voltage that changes fan motor M.
TD among the figure is general neon tube, and it is similar with two-way silicon trigger tube on electrical property, and it is big to trigger power.In addition, it can also make tutorial light usefulness, is a kind of trigger tube of inexpensive dual-use material.Second resistance R 2 and second capacitor C 2 are provided with in order to suppress overvoltage.
As scheme shown in the accompanying drawing: after energized; Supply voltage through first resistance R, 1, the second resistance R 2 to the charging of first capacitor C 1, after the peak value of the voltage at first capacitor C, 1 two ends reaches the blocking voltage of neon indicator TD; Neon tube is bright, the conducting thereby bidirectional thyristor KS is triggered.The size of bidirectional thyristor KS trigger angle is controlled through changing first capacitor C, 1 duration of charge Changshu.
Just can control bidirectional thyristor KS through the size that changes second resistance R 2 triggers on any phase place.If second resistance R 2 is too big; With making first capacitor C, 1 voltage reach the situation that curve descends; This moment, the voltage at first capacitor C, 1 two ends rose very slowly; The voltage that may make first capacitor C, 1 two ends can't reach the blocking voltage of neon indicator TD between whole mains half-cycle, promptly bidirectional thyristor KS can conducting; That is to say with changing to have some limiting values when slide rheostat W controls the brightness of rotating speed or neon indicator TD of fan, it is then uncontrollable to be lower than this limiting value.Therefore,, can adopt first resistance R 1 and first capacitor C 1 to help first capacitor C, 1 voltage and rise, make its blocking voltage that reaches neon tube TD, to trigger bidirectional thyristor KS as slide rheostat W during greater than limiting value.Hence one can see that, and slide rheostat W is used for the average current of control load.
