Abstract

The invention relates to an application method of a load power supply with characteristically-varied negative resistance, and in particular relates to an application method of a load power supply with characteristically-varied negative resistance for realizing a multifunctional control circuit. The application method of the load power supply comprises the following steps of breaking down a load to be started so as to realize the starting; and carrying out the restoration step for the started load through a restoration power supply cabinet, and carrying out the starting step also through the restoration power supply cabinet. The starting function and the restoration function can be realized through the same restoration power supply cabinet, so that the number of the equipment such as a high-voltage starting power supply can be reduced.

Description

technical field [0001] The invention relates to a method for using a load power supply with varying negative resistance characteristics, in particular to a method for using a control circuit for implementing multiple functions with a load power supply with varying negative resistance characteristics. Background technique [0002] The demand for polysilicon mainly comes from semiconductors and solar cells. According to different purity requirements, it is divided into electronic grade and solar grade. From the current development process of international solar cells, it can be seen that its development trend is monocrystalline silicon, polycrystalline silicon, ribbon silicon, and thin film materials (including microcrystalline silicon-based thin films, compound-based thin films and dye thin films). Polycrystalline silicon is the direct raw material for the production of monocrystalline silicon, and is the basic electronic information material for semiconductor devices such a...
