Description

technical field [0001] The invention relates to a high-voltage and low-voltage conversion device used in the field of magnetron sputtering vacuum coating, which can meet the requirements of using different bias voltages in the coating process, and can reduce the risk of high-voltage electric shock during the high-voltage conversion process. Background technique [0002] A variety of bias voltages are required in the process of magnetron sputtering. Due to the frequent switching of bias voltages, it is often necessary to switch the electrodes manually, which complicates the process of magnetron sputtering. It will increase the risk of electric shock and cause personal injury. Moreover, most of the transfer switches used here are external switches for manually controlling the electrode transfer. Although there is a certain guarantee for the operator, the high voltage is still switched manually, and the danger still exists. Therefore, the switch control is further integrated i...
