Abstract
The invention discloses a kind of method that thyristor control realizes inductive load cycle zero cross fired Power Regulation, specially：During inductive load cycle zero cross fired Power Regulation is carried out, in 4 cycles of starting of the conducting in cycle T, turned on using phase-shifting trigger control, be stepped up phase shifting angle, until all-wave is turned on.The present invention can make inductive load have a soft start-up process, slow down in the impact in a flash to electrical network that switches on power, and prevent tripping operation.
Description
Technical field
The invention belongs to IGBT group control field, relates in particular to a kind of thyristor control and realizes inductive load week
The method of ripple zero cross fired Power Regulation, especially inductive load（For example：Transformator etc.）Realize that cycle zero cross fired is controlled.
Background technology
At present, IGCT cycle zero cross fired control is mainly used in resistive load（For example：It is electric filament lamp, resistance furnace, roasting
Case etc.）.If simple cycle zero cross fired control is used in inductive load, as inductive load is switching on power or is disconnecting
Power supply in a flash, can produce back-emf voltage, and the peak value of this voltage is far longer than load Alternating Current Power Supply device and can bear
Magnitude of voltage, it is easy to cause the momentary overload of electrical network, or even cause tripping operation.
The content of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, there is provided a kind of thyristor control realizes sense
Property load cycle zero cross fired Power Regulation method, the present invention can make inductive load have a soft start-up process, slow down and connecting electricity
Source impact in a flash to electrical network, prevents tripping operation.
For achieving the above object, the technical solution used in the present invention is as follows：
A kind of method that thyristor control realizes inductive load cycle zero cross fired Power Regulation, it is characterised in that：It is negative perception is carried out
During carrying cycle zero cross fired Power Regulation, in 4 cycles of starting of the conducting in cycle T, turned on using phase-shifting trigger control,
Phase shifting angle is stepped up, until all-wave is turned on.
Using it is an advantage of the current invention that：
The present invention compensate for the difficult problem that inductive load is unable to zero cross fired control；As, in the cycle of conducting, only front 4 all
Ripple is phase-shifting trigger, and follow-up cycle is all sine wave, so solving the problems, such as that phase-shifting trigger harmonic content is higher；Greatly improve
The power factor of inductive load.And harmonic content is little, with respect to phase-shifting trigger mode more energy-conservation.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Specific embodiment
A kind of method that thyristor control realizes inductive load cycle zero cross fired Power Regulation, is carrying out inductive load cycle mistake
During zero triggering Power Regulation, in controlling cycle T, there are the cycle of conducting and a cycle of shut-off, the conducting in the cycle T rises
Begin in 4 cycles, turned on using phase-shifting trigger control, be stepped up phase shifting angle, until all-wave output is turned on.There is inductive load
One soft start-up process, slows down in the impact in a flash to electrical network that switches on power, and prevents tripping operation.
