模拟电子 二极管导通开关稳压器引发的故障时间
 
Most circuit designers are familiar with diode dynamiccharacteristics such as charge storage, voltage dependentcapacitance and reverse recovery time. Less commonlyacknowledged and manufacturer specifi ed is diode forwardturn-on time. This parameter describes the timerequired for a diode t ...
电源技术 手持式高功率电池充电器
 
As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, ...
电源技术 基于FPGA的高度集成DCDC稳压器
 
In a recent discussion with a system designer, the requirementfor his power supply was to regulate 1.5Vand deliver up to 40A of current to a load that consistedof four FPGAs. This is up to 60W of power that must bedelivered in a small area with the lowest height profi lepossible to allow ...
电源技术 笔记本电脑的功率调节系统
 
Notebook and palmtop systems need a multiplicity ofregulated voltages developed from a single battery. Smallsize, light weight, and high efficiency are mandatory forcompetitive solutions in this area. Small increases inefficiency extend battery life, making the final productmuch more usab ...
单片机编程 基于IC卡的新型供暖计费系统设计
将现行的供暖计费方式由按建筑面积计费变为按消耗的热能计费是供暖计费方式发展趋势，为了满足这一计费方式变化的需要，设计了基于IC卡的预付费式新型供暖计费系统，通过测量用户采暖系统进出口的温度和流量，计算用户消耗的热能，利用IC卡记录用户预付费的金额和当年热能的单价，根据热能消耗和当年热能的单价计算用户采暖 ...

In engineering, compensation is planning for side effects or other unintended issues in a design. The design of an invention can itself also be to compensate for some other existing issue or exception.
One example is in a voltage-controlled crystal oscillator (VCXO), which is normally affected not ...
