电源技术 模块化无功补偿技术的发展及应用
在采用电容器对电网进行无功功率补偿的同时，谐波对电网造成的不利影响已是不可回避的问题，也就是说不考虑谐波的影响因素，而单纯进行无功补偿的时代已经过去，对负载系统进行无功补偿的同时，必须兼顾对谐波治理。

电源技术 单片同步稳压器驱动外部元件负载
 
The LTC®3414 offers a compact and efficient voltage regulatorsolution for point of load conversion in electronicsystems that require low output voltages (down to 0.8V)from a 2.5V to 5V power bus. Internal power MOSFETswitches, with only 67mW on-resistance, allow theLTC3414 to deliver ...
电源技术 如何运用DC-DC升压调节器
 
便携式电子器件(如智能手机、GPS导航系统和平板电脑)的电源可以来自低压太阳能电池板、电池或AC/DC电源。电池供电系统通常将电池串联叠置以实现更高的电压，但由于空间不足，此技术未必总是可行。开关转换器使用电感的磁场来交替地存储电能，并以不同电压释放至负载。因为损耗很低，所以开关转换器是个不错的高 ...
电源技术 MSP430与bq电量计间采用SMBus通信接口的宽输入电池充电器
本应用报告描述了一个具有宽电压输入的智能电池充电器。其中的参考设计实现了在MSP430微控制器和兼容SMBus的电池电量计之间进行通信的系统管理总线（SMBus）协议。MSP430 器件通过SMBus 从电量计获取电压、电流和其它一些参数，之后通过调节输出到dc/dc变换器模块的PWM 占空比来传递电池所需的电量。
