Abstract
The utility model relates to a passive switching power source device connected in series in an AC electric appliance switching circuit, which comprises a voltage stabilizing diode and a capacitor which is connected in parallel with the voltage stabilizing diode, wherein, the voltage stabilizing diode and an operation device are connected to form a closed loop. The utility model is characterized in that the output ends of an impedance rectification component and a voltage transformation component are respectively connected with the power supply output end of the voltage stabilizing diode. The impedance rectification component and a load are connected in series to form a loop. The loop is formed by that the load, a load switch and the voltage transformation component are connected in series orderly; thus, whether a circuit exists in an open circuit or a closed circuit or semishrouded circuit, the operation device can obtain a regulated power supply, and a load loop can not generate the problem that the load loop can not be fully used because of loss of voltage.
Description
The utility model system utilizes the electric power that is connected on ac electric apparatus switch place, when operating means (as timer, the inductor) required electric power of this electrical equipment is operated in supply, and the electric power when obtaining switch closure with a component for variable-pressure.
Usually in the time of will on appliance mains switch, installing operating means such as remote control, timing or induction additional, must consider this remote control, regularly, the necessary power supply of operator such as induction supplies with.As switching circuit is only arranged, circuit has only voltage and no current between two-terminal when open circuit, electric current is only arranged and no-voltage when closed circuit, unless there is a power supply to supply with in addition, otherwise can't give operator necessary stabilized power supply with voltage between switch ends or electric current.And general family power distribution circuit switch just is connected on the switch ends of electrical circuit mostly, as when desiring to install additional operator such as remote control or timing, induction, then because of suitable power supply can't be provided, feels more difficult when installing operating means additional and make.
For addressing the above problem, one of solution of commonly using is series connection one impedance component (for example: electric capacity, resistance or inductance) 1 and one voltage stabilizing didoe 2 in switch loop (as shown in Figure 1); When switch was opened a way, voltage produced low-voltage dc power supply supply operating means 3 through the impedance step-down of this impedance component 1 through voltage stabilizing didoe 2; And when switch when being closed, electric current is then through loading 4 to voltage stabilizing didoe 2, still can supply operating means 3 suitable voltage, electric current.
But the shortcoming of foregoing circuit structure is that 2 step-downs are 10 volts as voltage stabilizing didoe, and the 4 necessary voltages that lose 10 volts of then loading can't make full use of, and this load 4 must lower its function.For instance, when voltage stabilizing didoe 2 step-downs are 10 volts, then load and 4 must lose 10 volts voltage; Suppose that load 4 is 110 volts voltage, 100 watts power, and 10 volts of voltage stabilizing didoe 2 step-downs, 4.5 watts the power of then having an appointment can not be used to load 4, (its computing formula: 100W * 100/110=90.9W, 100W-90.9W=9.1W) if but the power of 1 watt of 3 need of operating means, then it is done 8.1 watts and will waste loss, produces easy situation, makes parts heating, energy unnecessary consumption, does not conform to the electricity consumption economic principle.
The purpose of this utility model provides a kind of passive switch supply unit in the appliance switch ac power supply circuit of being connected on of the defective that can overcome prior art.
The utility model is achieved in that it comprises voltage stabilizing didoe and the electric capacity in parallel with it, this voltage stabilizing didoe and operating means are (as remote controller, timer or inductor) connect into the closed-loop path, be characterized in one with load be in series the impedance rectification part that constitutes the loop and one with load, on-load switch is according to the component for variable-pressure that is connected into the loop, and the output of this impedance rectification part and component for variable-pressure is connected with the power supply output of this voltage stabilizing didoe, like this, when on-load switch is in out, the state of pass or half-open semi-closure, the stabilized voltage power supply that provided by this voltage stabilizing didoe all can be provided operating means, and the defective that can't make full use of because of this voltage stabilizing didoe step-down can not take place this load.
Further, above-mentioned impedance rectification part comprises impedance electric capacity and connected rectifier, and it makes when on-load switch is opened a way and obtains power supply by rectifier;
Above-mentioned again component for variable-pressure comprises transformer that is connected to this on-load switch after one and the rectifier that is connected with this transformer, it makes when on-load switch is closed, this primary winding is in series through on-load switch and this load, and is boosted after this rectifier provides the power supply of operating means by secondary winding.
Advantage of the present utility model is that original switching circuit can add an operating means, and no matter circuit is when open circuit, closed circuit or half-open semi-closure, and operating means all can obtain a stable power; And the problem that load circuit loss voltage can't make full use of can not take place because of the step-down of voltage stabilizing didoe in this load.
Accompanying drawing of the present utility model is simply described as follows:
The circuit theory diagrams of switching circuit serial operation device are commonly used by Fig. 1 system.
Fig. 2 is circuit theory diagrams of the present utility model.
Below we provide better embodiment of the utility model according to Fig. 2.
See also shown in Figure 2ly, the utility model mainly lies on the switching circuit series connection one an impedance rectification part 50 and a component for variable-pressure 70, so that supply the voltage and the electric current of an operating means 3; Wherein, this impedance rectification part 50 lies in series connection one an impedance electric capacity 5 and a rectifier 6 in the load switching circuit; This component for variable-pressure 70 ties up to series connection one power transformer 7 and a rectifier 8 in a load 4 and the operating means 3.
When load switching circuit is when open circuit, obtain power supply by this impedance electric capacity 5, rectifier 6, the required power supply of supply operating means 3 after voltage stabilizing didoe 9, electric capacity 10 give voltage stabilizing; And when closed circuit, this voltage source disappears, and changes and obtains electric current by power transformer 7, rectifier 8, is supplied to operating means 3 through voltage stabilizing didoe 9, electric capacity 10 voltage stabilizings equally.So when no matter circuit was in open circuit, closed circuit or half-open semi-closure (for example light adjusting circuit), operating means 3 all can obtain a stable power.And load 4 can be because of the step-down of the voltage stabilizing didoe 94 loss voltages situations that can't make full use of of loading, so the also attenuating of the function of this load 4.
If the design of power transformer 7 of the present utility model is enough to supply the required power supply of operating means 3 just, then more there is not the situation that wastes energy.
By the foregoing circuit structure, this power transformer 7 and rectifier 8 are directly to be series on original switching circuit, this power supply that operating means 3 is fit to can be provided by this, improvement is commonly used when switching circuit is closed circuit, and electric current is through loading to the shortcoming of voltage stabilizing didoe supply operating means 3 required voltages, electric current; And as desire on load switching circuit, to install additional remote control, regularly, during operating means such as induction, must not remove original switching circuit fully, only additional this component for variable-pressure 70 must be installed on former switching circuit and operating means 3 gets final product, install additional conveniently, and component for variable-pressure 70 can provide the electric current of an equilibrium of supply and demand to give operating means 3, do not have the problem that the improper consumption of the energy takes place, meet the electricity consumption economic principle.
