The invention discloses electrophoresis power supply equipment, which mainly comprises a PLC controller, a main circuit, an AC power supply control circuit, a data collecting and amplifying circuit and an electric cabinet door surface, wherein the PLC controller is connected with the main circuit, the AC power supply control circuit, the data collecting and amplifying circuit and the electric cabinet door surface separately; the main circuit comprises a three-phase full-wave rectifier circuit, a filter circuit, a full-bridge inverter circuit, a high-frequency power transformer and a rectifier and filter output circuit; and an IGBT switching device is adopted by the full-bridge inverter circuit. The pollution of an electrophoresis power supply to power grid harmonics in the prior art can be overcome; the control accuracy is improved; the output ranges of voltage and current are increased; and meanwhile, automatic or manual adjustment on the temperature or the argon flow is achieved through the PLC controller, so that the control accuracy of a three-dimensional electric field control electrophoresis boron and phosphorus removal process is improved.
Description
technical field [0001] The invention relates to the technical field of electrophoresis boron and phosphorus removal controlled by a three-dimensional electric field, and in particular relates to an electrophoresis power supply device. Background technique [0002] Three-dimensional electric field-controlled electrophoresis boron and phosphorus removal process is one of the important processes in the Gossilicon method. Depth and controllable removal of boron and phosphorus are very important for the quality assurance of polysilicon materials for ingot casting. Precisely control the electric field and its temperature field, so that the impurities in the silicon liquid move properly in the crucible according to the simulated movement path. By implementing a direct current electric field, the phosphorus and boron that are separated on both sides of the silicon in the periodic table of elements are extracted respectively. Put the falling liquid silicon into the purification bag w...
