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 ...
电源技术 DCDC模块输入端电压反加后的影响分析
在航天等空间产品中使用的分布式供电系统中，总体电路一般只提供27~30 V的直流一次电源，各单机产品大多采用DC/DC模块将该一次电源转换为所需的二次电源，并实现一次地与二次地的隔离。分析了INTERPOINT公司的DC/DC模块的输入端反接后，输入电压对DC/DC模块、电源保护滤波电路及负载的影响，通过仿真与验证试验，得出电源模 ...
