Description

The electronic power adjuster

The utility model relates to a kind of power governor, belongs to a kind of Power Conditioning Unit.

At present, the variable power of household electrical appliance such as electric rice cooker is regulated by secondary or three step switch transforming gear and is realized that power regulating range is single, and limitation is big.

The purpose of this utility model is to design the electronic power adjuster that a kind of power output is adjustable continuously, be fit to each specification power household electrical appliance use.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic power adjuster, include shell, regulating element, circuits for triggering, control circuit, its special character is that described regulating element is connected in series mutually with charging resistor, the charging capacitor of circuits for triggering, be connected in series a trigger tube to the control circuit control end in charging resistor, charging capacitor joint, control circuit two conduction terminal are in parallel with the regulating element that is connected in series, circuits for triggering, and control circuit also is serially connected in the power circuit simultaneously.

Described regulating element adopts variable potentiometer to constitute, and control circuit adopts the control element controllable silicon to constitute, and the trigger tube of circuits for triggering adopts bidirectional diode.

The size of power governor power output of the present utility model is determined by electric current by control circuit, control circuit be the time slot decision that triggers the control element conducting and end by the trigger voltage of circuits for triggering by electric current, and this conducting is regulated by regulating element with the time numerical value that ends.

When output inserts load, supply voltage charges to charging capacitor through load, regulating element, when voltage on the electric capacity reached the trigger tube breakover voltage, trigger tube punctured, conducting, and trigger voltage is added to the control element control end, make the control element conducting, load powers up, and when the voltage on the charging capacitor is released into when being lower than the control element conducting voltage, control element ends, the load dead electricity is finished a circulation.The size of the angle of flow is determined by the circuit time constant that regulating element, charging capacitor constituted, change regulating element numerical value and can cause that the circuits for triggering time constant changes, thereby the time ratio of control conducting, shutoff control element, average power in the load is changed, reach the purpose of step-less adjustment power.

The household electrical appliance that electronic power adjuster of the present utility model is adjustable continuously, be fit to all size power use, can effectively overcome the needs gear shift of ordinary electrical home appliance power adjustments and the potential pulse that produces impacts, and are applied widely.

Accompanying drawing and drawing are described as follows:

Fig. 1-the utility model block diagram;

Fig. 2-the utility model most preferred embodiment circuit diagram.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing, be used to further specify the utility model.

Most preferred embodiment, with reference to figure 1, Fig. 2, the electronic power adjuster of this embodiment comprises the shell of tape input output, regulating element adopts variable potentiometer W, circuits for triggering include charging resistor R, charging capacitor C, trigger adopts bidirectional diode D, variable potentiometer W is connected in series mutually with charging resistor R, charging capacitor C, at R, C joint serial connection bidirectional diode D controllable silicon T control end to the control circuit employing, controllable silicon two conduction terminal are in parallel with the W that is connected in series, R, C, also are serially connected in the power circuit simultaneously.
