电源技术 DC Power 基于Mega8数控电源
内涵PCB及其原理图(原PCB为crazyboye所制,Gavin尽量把双面改一面,因为学校没有制版机)
电源技术 软开关APFC倍频感应加热电源的研究
随着功率开关器件的发展,电力电子装置日益小型化和高频化,电气性能大幅提高,但是随之产生的高次谐波却对电网造成严重污染。在电力电子设备中,整流器(AC/DC变流器)占有较大的比例,是主要的污染源。由于固态感应加热电源对于电网呈现非线性特性,从电网中输出的电流就不是标准的正弦曲线。高频谐波电流对电力设施产生 ...

电源技术 电源调整与虚拟地
Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the ...
