电源
在现代电子世界，电子设备数不胜数，电力需求同样大又各不相同。这些不同之处可能存在于电压需求或电流需求中，或二者兼而有之。然而，至少从消费者的角度来看，仅有单一电源可用，即标准的交流电源壁装插座。这在一定程度上说明了对现代电源模块的需求。电源模块专为提供特定的电压和电流输出而设计，通常因提供给设备的输入电力而异。这种模块既是输出装置，也是输入装置，在两者之间进行某种形式的转换或保护。
电源的供电方式多种多样。多数现代电源为开关式，这意味着它们利用功率晶体管在内部修改信号，同时保持低功耗。一些电源将交流电力信号转换成直流；这种电源一般多见于笔记本电脑和计算机设备。其他电源可能以另一种方式将直流转换成交流。随着太阳能装置的广泛应用，这种电源越来越普及。简易设计提供交流至交流转换，通常使用升压或降压变压器进行电压变换，产生相控信号。

AC to DC Conversion with Full & Half-Wave Linear Rectifiers
Alternating current (AC) power is responsible for running many types of electrical appliances. But what if you need direct current (DC) power to operate a computer or LED? Converting AC to DC uses a configuration of diodes—and in some cases a transformer—known as a linear rectifier, or just a rectifier.
Speed Does Not Kill: Power Supplies with Fast Switching Frequency Just Got a Lot Safer
Isolated power supply systems are prevalent in server systems, industrial applications, and telecommunication and networking equipment. In this bandwidth-hungry age of the Internet of Things (IoT), a growing number of these systems need to be efficiently powered, driving up the need for power-efficient, cost-effective solutions. This paper from Silicon Labs examines significant innovations in this area and exciting new products that are now available with high-speed switching capability, offering increased system efficiency and a lower component size.
USB Type C and USB 3.1 Gen 2 – Clarifying the Connection
The USB Type C connector includes many feature enhancements over previous USB connector standards. This paper helps engineers understanding these improvements, so they can utilize this connector and the various signal specifications in the proper manner to boost performance in their design with CUI’s leading USB connectors.
