Embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises shell, is provided with electronic switching circuit, control circuit and voltage stabilizing power supplying circuit in shell, also is respectively arranged with control input end and output end of stabilized voltage supply; Wherein electronic switching circuit connects load, control circuit and voltage stabilizing power supplying circuit respectively, and the control input end is connected to control circuit, and voltage stabilizing power supplying circuit is connected to power output end.Electronic switch is made up of bridge rectifier QL, unidirectional controllable silicon S CR1, resistance R 3, voltage stabilizing didoe D1; Control circuit and voltage stabilizing power supplying circuit are made up of unidirectional controllable silicon S CR2, resistance R 4, voltage stabilizing didoe D2, resistance R 1, storage capacitor C1; The control input end is made up of LED, resistance R 2.
Operation principle of the present utility model is as follows: in insulation crust, electronic switching circuit, control circuit and voltage stabilizing power supplying circuit, order are electrically connected, the tie point of voltage stabilizing didoe D2 and current-limiting resistance R1 is the output of positive source in the voltage stabilizing power supplying circuit, and the negative pole of DC voltage-stabilizing power supply circuits connects with reference to ground; The connecting line of entire circuit and load and AC power has only two.
The closed condition power supply the principle is as follows as shown in Figure 2:
When electronic switch disconnects, i.e. load is not worked, AC power U～charge, externally provide the voltage stabilizing power supply through R1 current limliting D2 voltage stabilizing to storage capacitor C1 by the load earial drainage.
The opening power supply the principle is as follows as shown in Figure 2:
Increase control signal and trigger controllable silicon SCR 2 conductings outside the control input end is subjected to, this moment, the voltage at the R4 two ends constantly rose, and pass through voltage stabilizing didoe D2 and charge to storage capacitor C1, DI conducting when voltage reaches voltage stabilizing didoe D1 voltage stabilizing value, produce the electric current that triggers controllable silicon SCR 1 conducting, the SCR1 conducting causes the SCR2 zero-current switching, has finished a process to storage capacitor C1 charging; In the alternating current zero passage in a flash, controllable silicon SCR 1 must be closed, and the controllable silicon SCR under the triggering state 2 continues conducting ever since, triggers the conducting of controllable silicon SCR 1 subsequently, and keeps the continuity of load conducting.This shows: in each cycle of alternating current, all can have electric current that storage capacitor C1 is charged, the voltage of DC voltage-stabilizing output is maintained.
In above-mentioned, no matter load is to close or open, and the charging of storage capacitor C1 can not interrupted, thus guaranteed switch open or closed condition under the voltage stabilizing power supply still can work sustainedly and stably.
At circuit shown in Figure 3 is the embodiment that the utility model is applied to remote control switch;
Its operation principle is as follows: output, the signal output part that the required working power of remote-control receiving circuit is connected to stabilized voltage power supply is connected to the control input end of electronic switch supply module.If controllable silicon SCR 1 is ended during initial condition, load is not worked; When remote-control receiving circuit is received remote signal, transmit a high level to the control input end after effectively decoding by receiving circuit, trigger controllable silicon SCR 2 conductings, loaded work piece; When remote-control receiving circuit is received remote signal again, by receiving circuit effectively decode bistable circuit upset and output low level, controllable silicon SCR 2 signals out of hand and ending, load quits work, and gets back to initial condition.So far, be a work period.
In the above-described embodiments, remote-control receiving circuit can be the radio wave remote-control receiving circuit, can be remote-control receiving circuits such as infrared ray, visible light, ultrasonic wave also, can constitute corresponding remote control switch.
