Problems solved by technology

[0006] In view of the defects in the prior art, the purpose of the embodiment of the present application is to solve the problems in the prior art that do not take into account the state change of the crystal itself by providing an adaptive regulation method and system for crystal growth power supply parameters. And the temperature difference in the crystal furnace leads to low flexibility and increased probability of sintering failure. It is proposed to dynamically adjust the preset output parameters in combination with the real-time state of crystal sintering, thereby improving the control of power output parameters. The technical effect of flexibility and intelligence

Abstract

The invention discloses a self-adaptive regulation and control method and system for crystal growth power supply parameters, and the method comprises the steps: obtaining a first control parameter according to a first crystal growth power supply; obtaining first particle size characteristic information; inputting the first particle size characteristic information and the first temperature information into a particle size change trend prediction model to obtain first particle size change trend information; sorting the trend change probability according to a preset sorting rule to obtain a first sorting result; obtaining a first particle size change trend according to the first sorting result; judging whether the first particle size change trend meets a preset particle size change trend or not; and if the preset particle size change trend is met, controlling the first crystal growth power supply to output the first voltage amplitude, the first current amplitude and the first pulse frequency. The technical problems that in the prior art, the state change of the crystal and the temperature difference in the crystal furnace are not considered, so that the flexibility is low, and the probability of sintering failure is increased are solved.
