Abstract
The utility model relates to a multi-functional power supply controller which can realize pressure adjusting and time delay power down function. When the circuit works by light adjusting manner, a potentiometer in pressure adjusting circuit is adjusted to change a triggering angle of a bidirectional thyristor and change the average voltage at the two sides of an electricity utilization machine. When the circuit works by time delay power down manner, the pressure adjusting circuit is cut by a key and the power down time delay circuit is connected. Along with the gradual accumulation of electric charge at capacitance, the trigger current at the bidirectional thyristor reduces continually until the turnon of the bidirectional thyristor can not be kept and the multi-functional power supply controller will stop working.
Description
The utility model relates to a kind of multifunctional electric power controller.
At present commercially available power-supply controller of electric function all is more single in general, can not satisfy the demand of our actual life, use cumbersome, so brought inconvenience to the user.
The utility model multifunctional electric power controller can be realized pressure regulation and delay cut-off function.
The structure of the utility model multifunctional electric power controller is such: the trigger end of bidirectional thyristor connects pressure-control circuit and power-off delay loop, when circuit is worked with dimming mode, potentiometer in the scalable pressure-control circuit changes the trigger angle of bidirectional thyristor, to change the average voltage at electrical appliance two ends; When circuit is worked to postpone power-down mode, to utilize telegraph key to disconnect pressure-control circuit, and connection power-off delay loop, accumulation gradually along with electric charge on the electric capacity, trigger current on the bidirectional thyristor constantly reduces, until the conducting that can not keep bidirectional thyristor again, this multifunctional electric power controller will quit work this moment.
The utility model multifunctional electric power controller has overcome the power supply shortcoming of present use, can realize pressure regulation and delay cut-off function, and it is cheap for manufacturing cost, volume is little, consumption is minimum.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is circuit theory diagrams of the present utility model.
The embodiment of the present utility model that provides below in conjunction with accompanying drawing.
220V civil power live wire end is connected electrochemical capacitor C3 through between telegraph key K1, electrical appliance and ground terminal, the negativing ending grounding line end of C3, and connect inductance L, the other end of L links to each other with the common port of C3 and bidirectional thyristor SCR; With the resistance R 1 formation resistance branch that is in parallel, this branch road serial connection capacitor C 1 forms pressure-control circuit behind the potentiometer W1 series resistor R2; Resistance R 3, bidirectional thyristor ST, telegraph key K2 are in series, and this branch road is in parallel with the series arm of diode D1 and capacitor C 2, form the power-off delay loop, and wherein push type telegraph key K3 is connected on the C2 two ends; This power-off delay loop is connected on the link of the resistance branch that C1 and W1, R2, R1 form on the positive extreme direction of diode D1, the other end is connected on the trigger end of bidirectional thyristor SCR; The two controlled pressure-control circuit two ends that terminate at of bidirectional thyristor SCR.
