Abstract
The general regulator on master phase is provided without an amplifying trigger current link, so the load capacity is limited under 4KW. The utility model relates to a voltage regulator capable of amplifying trigger current at the master phase, which is added with an amplifying trigger current link which is composed of a bidirectional assistant thyristor KS[2] and an adjustable resistor R[2] in series connection. The control electrode of the KS[2] is connected with one end of a DB[3], and the negative pole of the KS[2] is connected with the positive pole of the KS[1]. The utility model both increase the loading capacity and bring complementarity between the two triggering modes of the two bidirectional thyristors, and the gate pole triggering mode is uniform. Therefore, the utility model eliminates even harmonics, and the system structure of voltage adjusting and speed adjusting can be greatly simplified.
Description
The utility model belongs to the electrical appliance field, particularly a kind ofly amplifies the voltage regulator of trigger current on mutually at this.
That uses at present does not amplify the trigger current link at this voltage regulator of going up mutually, so its load capacity is restricted, generally below 4kW.For example utility model CN2053400U discloses a kind of electric rice cooker voltage regulator, and its bidirectional diode ST is by resistance R
3Protection, variable resistor R
1', resistance R
2Form charge-discharge circuit with capacitor C, bidirectional diode ST triggers the bidirectional triode thyristor G utmost point, changes the size of the angle of flow, and output voltage changes, and becomes resistance because R ' is fixed on one, and the output voltage that makes voltage regulator is a definite value.This regulator only is applicable to the household electrical appliance that power is lower, and the pressure-regulating portion of the multi-purpose socket that utility model CN2052965U provided divides circuit and CN2053400U basic identical.
Adopt the pressure and speed regulating system of this voltage regulator,, must trigger be set in control circuit, make system configuration very complicated if capacity is bigger.
The purpose of this utility model provides a kind of voltage regulator that amplifies the trigger current link that has, and makes main circuit and circuits for triggering form an integral body, and load capacity is significantly enlarged.
Another purpose of the present utility model provides a kind of power supply, continuously adjustable voltage regulator is provided for R or R-L load.
According to the utility model, on original voltage regulator, increase by one and trigger and amplifying element, promptly set up an auxiliary bidirectional triode thyristor.Resistance R by former voltage regulator
1Power supply signal is taken out mutually from this, and through the resistance-capacitance circuit time-delay, after the capacitor charging, the bidirectional trigger diode conducting produces electric current and remove a phase load after auxiliary bidirectional triode thyristor amplifies.
Amplify the trigger current voltage regulator mutually according to of the present utility model, owing to be provided with the trigger current amplifying element, load capacity obviously increases, and gate pole triggering mode symmetrical complement has been eliminated even-order harmonic.When being used for control system, its control mode can greatly be simplified.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is that existing phase current triggers the voltage regulator schematic diagram.
Fig. 2 of the present utility modelly amplifies the schematic diagram of the voltage regulator of trigger current on mutually at this.
