Background
With the application development of the switching power supply, in some occasions with special requirements, especially when the same load is under the same voltage, some circuit power supply loads requiring more precision and stability are easily interfered by the same-position load, especially when the inductive loads with more inductive loads, such as various motors, are provided, because the interference generated by the motors during starting is larger, other loads on the same path are easily influenced.
At present, the switching power supply in domestic market is mainly designed by a single-path same-voltage or multi-core different-voltage switching power supply and is additionally provided with a plurality of stable feedback circuits. However, with the further development of technology and market, especially the further maturity of market, all products need to be normalized, especially when the electric and electronic devices on the market are subjected to 3C certification, especially in a power module, when the devices detect leakage current, if each individual device is individually connected to a power adapter, the leakage current of a safety capacitor is inevitably increased, and therefore the devices cannot be tested and passed in safety standard test. However, if a switching power supply is connected to devices with the same voltage at the same time, in the case that all loads are loaded together, especially in the case that some inductive loads are relatively large, various crosstalk and overvoltage influences on the loads on the same path are particularly large, even other loads on the same path may be burned due to overvoltage under the condition of high-power inductive loads, and due to the circuit characteristics of the inductive loads and the capacitive loads, the inductive loads and the capacitive loads can generate large interference influences on the devices on the same path when starting and stopping.
