Switching power supplies have become the protagonist of our circuit design, and can even be said to have become an inseparable part of the industry's development. Compared with traditional linear po...[Details]

In recent years, with the large-scale construction of 3G networks and the rapid popularization of smart phones, the era of mobile Internet has arrived. As an operating system launched by Google, A...[Details]

High power semiconductor light-emitting diodes have great prospects in replacing incandescent lamps, but the technical problems must be solved first. The geometric structures of s...[Details]

1 Introduction As energy depletion and environmental pollution become increasingly serious, countries are increasingly eager for green energy, which has led to unprecedented development of phot...[Details]

　　The LED light bar can achieve 360-degree light source without adding lens, which makes people feel like returning to the traditional incandescent lamp. LED light bar has many application advantag...[Details]

　　Analysis of the schematic diagram of DC low voltage regulated power supply: 　　The VD1-VD4, R1, C1, and C2 of the switching power supply part form a rectifier filter circuit. NE555 and R2, R3, C4, V...[Details]

This paper uses supercapacitors for rectification and filtering, and designs and implements them. Tests prove that supercapacitors can be used for rectification and filtering at the output end of the...[Details]

LED is an electroluminescent light source. Its luminescence principle is that when a forward voltage is applied to both ends of the PN junction, the holes in the P region will flow to the N region. Th...[Details]

　　"The more you discharge a lithium-ion battery, the more it wears out," said Tom Hartley, an electrical engineering professor at the University of Akron who helps NASA study ways to extend battery l...[Details]

I recently heard a statement that the digital loop is identical to the analog loop at the output of a power converter . The statement goes like this: “To the end user, a power supply that uses a ...[Details]

0 Preface With the development of urban economy, the harm caused by induced lightning and lightning wave intrusion has greatly increased. Lightning rods on general buildings can only preve...[Details]

Part I. General Overview 1.1 Research Background Escalators are widely used in large shopping malls, supermarkets, airports, subways, hotels and other places. Most escalators work at rated operat...[Details]

On the secondary side of the power supply , the role of the rectifier and filter in the power supply is as easy to understand as their names. Their main task is to correct and filter the high-frequen...[Details]

Abstract: By adopting the peak current limiting method, the current limiting function can suppress the switch current of the power converter when the inductor current exceeds the threshold. However...[Details]
