Problems solved by technology
Due to the parallel relationship between the conversion circuit and the high-frequency rectification circuit, it is difficult to check the conversion circuit of the power supply and the electronic components of the high-frequency rectification circuit through traditional maintenance tools such as multimeters, clamp ammeters, and oscilloscopes during power supply maintenance. The performance of the device is inspected, and since the three-phase AC is rectified by the rectifier module, the DC current and voltage are relatively high, the conventional detection method has relatively large safety hazards, and there are few detection instruments suitable for high-frequency power supplies

Description
technical field [0001] The invention relates to the maintenance and detection of high-frequency switching power supply, in particular to provide a safe and reliable maintenance and testing tool for implementing the maintenance and detection of high-frequency switching power supply. Background technique [0002] In the electronic aluminum foil etching process, a large number of high-frequency switching power supplies are used as electrolytic power supplies. Most high-frequency switching power supplies achieve the purpose of increasing output power by connecting multiple groups of modules in parallel. Due to the parallel relationship between the conversion circuit and the high-frequency rectification circuit, it is difficult to check the conversion circuit of the power supply and the electronic components of the high-frequency rectification circuit through traditional maintenance tools such as multimeters, clamp ammeters, and oscilloscopes during power supply maintenance.
