Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
Only a small number of LED manufacturers can produce high-quality LEDs. For applications that are only used for simple indication, low-quality LEDs are sufficient. However, high-quality LEDs must...[Details]

At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
Currently, the commonly used solar cell technologies include monocrystalline silicon solar cells and polycrystalline silicon thin-film solar cells. Production process: Monocrystalline silicon solar...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
Current sensing in automotive applications includes controlling the current through solenoids and injectors. For example, during diesel injection, we rapidly increase the current to the induction i...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
As the electromagnetic environment in space becomes increasingly complex, the shielded cables used to transmit weak signals in the test system are easily affected by external electromagnetic distur...[Details]
Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]
