　　电源装置是电子电气设备中所不可缺少的部件，开关电源以其效率高、体积小、重量轻、电压适应性好等优点，受到相关行业的青睐。但目前存在的缺陷是电磁骚扰大，对环境或对其他设备造成不利影响。目前对于可变负载的开关电源，笔者所了解到的产品最低输出噪声电压也在70 mV以上。设计低电磁骚扰的开关电源，也就成了许多设计人员的希望，为此提出了种种方法。本例设计要点不同于常规技术，而是采取了从源头上对电磁噪声进...[Details]

TDK Corporation has recently launched the EPCOS B43659 series of solder-type aluminum electrolytic capacitors. The new series of components is a new generation of general-purpose products with a ...[Details]

After 10 years of research and development, an international research team composed of scientists from the University of Cambridge in the UK, the Commonwealth Scientific and Industrial Research Org...[Details]

UPS power supply testing generally includes two types: steady-state testing and dynamic testing. Steady-state testing is to test the phase voltage, line voltage, no-load loss, power factor, effici...[Details]

　　It can be said that in the design of a general switching power supply, a small amount of parasitic capacitance (100 femtofarads) from the switch node to the input lead will make you fail to meet ...[Details]

The development of water meters has a history of nearly 200 years. In the early stage, water meters from countries such as Britain, France, Japan and Germany have always occupied the Chinese water met...[Details]
