Embodiment

At first, see also Fig. 1～shown in Figure 3, the present invention mainly is made up of input unit 1, signal detection unit 2, control unit 3, output unit 4, timing unit 5, state of a

control unit

6 and 71,72 of a plurality of light-emitting diodes; Wherein:

This input unit 1, it includes AC power input jack 11 and control signal input unit 12, this AC power input jack 11 can supply the AC power input of 100～240v/50～60, this control signal input unit 12 then can be contact panel or is formed by touch controlled key collocation less radio-frequency module, can utilize touch-control, to push, stir each switch, button, in signal Input Control Element 3.

This signal detection unit 2, see also shown in Figure 4, it can be one zero friendships and detects device (ZenerCrossing Detector more, ZCD), it is connected with several diodes, resistance, electric crystal between two AC power supplies inputs, and be connected with Zener diode (Zener Diode) and electric capacity, and being connected to the input of optical coupler U1A again, the output of this optical coupler then is to connect in the Input Control Element 3.

This control unit 3, see also shown in Figure 5, it is that IC (DMPC0717EN) includes control signal processing unit 31, power adjustment unit 32, pulse wave position modulating signal generation unit 33, fundamental frequency generator 34, reservation/timing control unit 35 and state timing display unit 36, this power adjustment unit 32 then packing the demand of being available for users to is arranged and be designed to various segmentation loop controls unit eight sections loop control unit 321, with the no section fine setting control unit 322 that is Linear Control.

This output unit 4, its include exchange switch unit 41 and AC power output plughole 42, to exchange switch unit 41 be a power electronic element for this, as silicon control biphase rectification device (TRICA), this AC power output plughole 42 then can supply to be connected with any resistive or inductive AC power load, as: single phase alternating current (A.C.) motor, hair-dryer, electric fan, electric heater or incandescent lamp.

This timing unit 5, state of a control unit 6 and light-

emitting diode

71,72, it then can supply Displaying timer time or subscription time respectively, reaches the state to the light modulation or the speed governing of AC power load, with the control model of indicative control unit 3.

The present invention is on using, it is that the AC power of being imported via AC power input jack 11 is delivered to signal detection unit 2, to make this signal detection unit 2 produce a zero-crossing signal, the frequency of this zero-crossing signal can be 100Hz～120Hz, as shown in Figure 6, and be delivered to control unit, and the user can utilize control signal input unit 12 to send in the fundamental frequency generator 34 of control signal and Input Control Element 3, to make fundamental frequency generator 34 produce the internal control triggering signal, and deliver to control signal processing unit 31 and reservation/timing control unit 35, this reservation/timing control unit 35 is handled according to the internal control triggering signal, and

exports timing unit

5 and 6 demonstrations of state of a control unit to through state/timing display unit 36.

And this control signal processing unit 31 is according to the internal control triggering signal, come its reception is carried out signal processing by the zero-crossing signal that signal detection unit 2 produces, then see through power adjustment unit 32 and produce a pulse wave position modulating signal (Pulse Position Modulation with pulse wave position modulating signal generation unit 33, PPM), the pulse wave frequency range of this pulse wave position modulating signal can be 21.6KHz; Output frequency can be 100～120Hz; At this moment, if control signal input unit 12 is set at eight sections loop controls, this control signal processing unit 31 promptly sees through eight sections loop control unit 321, since order about pulse wave position modulating signal processing unit 33 and produce a pulse wave position modulating signal with eight sections control characteristics; And if control signal input unit 12 is set at and does not have section fine setting control (Linear Control), 31 of this control signal processing units see through does not have section fine setting control unit 322, produces the pulse wave position modulating signal with Linear Control characteristic to order about pulse wave position modulating signal generation unit 33.

And the interchange switch unit 41 of this output unit 4, it is when being subjected to the triggering of the pulse wave position modulating signal that pulse wave position modulating signal generation unit 33 produced, promptly the voltage waveform to input cuts, with the unlatching of control power output or close or increase, reduce power output, as shown in Figure 7, can control the AC power load that is connected in AC power output plughole 42.

By above explanation as can be known, the present invention utilizes zero friendship to get over the zero-crossing signal that detector is detected alternating current input power supplying, control unit then receives control signal and zero-crossing signal, and come zero-crossing signal is handled with control signal, to export a pulse wave position modulating signal to exchanging switch unit, for the AC power of input is cut, startup with the load of control AC power, close, increase power output, or minimizing power output, to reach digitisation control, and have waterproof with can not scintillant effect, and when light modulation or speed governing, reach Linear Control or segmentation control.
