电源技术 确保电解电容器的寿命长-LED灯泡为例
Abstract: Electrolytic capacitors are notorious for short lifetimes in high-temperature applications such asLED light bulbs. The careful selection of these devices with proper interpretation of their specifications isessential to ensure that they do not compromise the life of the end product. This ...
电源技术 零晶体管IC-IC设计一个新高度
Abstract: We can apply a BiCMOS integrated circuit with only resistors and no transistors to solve adifficult design problem. The mythically perfect operational amplifier's gain and temperature coefficient aredependent on external resistor values. Maxim precision resistor arrays are manufactur ...
电源技术 MR16 LED驱动MR16 LED灯与电子变压器兼容
Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from ...
电源技术 智能LED照明电子教材
Abstract: How smart is your LED lighting system? While LED lighting holds the promise of reducingenergy consumption and maintenance costs, smart LED lighting designs improve system performance in

Abstract: This application note details a step-by-step design process for the MAX16833 high-voltagehigh-brightness LED driver. This process can speed up prototyping and increase the chance for firstpass
电源技术 智能电网安全性
Abstract: The rapid build out of today's smart grid raises a number of security questions. In this article,we review two recent well-documented security breaches and a report of a security gap. These situationsinclude a 2009 smart-meter hack in Puerto Rico; a 2012 password discovery in grid di ...
电源技术 电能计量和安全性的智能电网
Abstract: It may sound trite, but it is definitely true: the smart grid has the potential to completely transform the energyindustry. However, smart meters and grid management alone will not ensure the success of the smart grid. Unliketraditional IT networks, smart grids require consideration of e ...
