In the era of rapid development of modern technology, switching power supplies are ubiquitous and serve as the "heart" of numerous electronic devices. So, how do we determine whether a switching power supply is qualified? This is a very crucial issue. Follow me, decrypt new knowledge today!500W Single Output Switching Power Supply1. Appearance inspectionFirstly, we need to conduct a visual inspection. A qualified switching power supply should have an intact appearance without any damage or deformation. At the same time, each interface should also be firm and reliable, with no signs of looseness.2. Performance testingSecondly, electrical performance testing is an essential step. We need to measure the accuracy and stability of the output voltage to ensure that it fluctuates within the specified range, and the ripple size should be controlled within a reasonable range. This is like the pulse of a power source, it must be stable and powerful.3. Load testingFurthermore, load capacity test...

In modern electronic devices, switching power supplies are widely used. However, even without load connection, switching power supplies still have no-load power consumption. So, how is this no-load power consumption generated?Firstly, internal circuit losses are one of the main reasons for no-load power consumption. The transistors, capacitors, inductors and other components inside the switching power supply, even when there is no current passing through, still have a certain amount of leakage current and equivalent resistance, which can lead to energy loss. For example, during the high-frequency switching process, the conduction and cutoff of the transistor will generate a certain amount of energy loss.Secondly, the consumption of control circuits is also a factor that cannot be ignored. The control circuit of the switching power supply needs to work continuously to monitor and adjust the output status of the power supply, even when it is unloaded. Although the electricity consumptio...
