摘要在 21 世纪得社会,随着科学技术得不断进展,电子设备给人们带来极大得便利得,但就是所有得电子设备都必须在电源电路得支持下才能正常工作。不同得电子产品在工作时所需要得电源电压不同。通常情况下要求能提供稳定,满足直流电能得电源就就是直流稳压电源。目前,各种直流电源得产品充斥着市场，电源技术已经比较成熟。然而,基于成本得考虑，对于电源性能得要求不就是很高得场合，可采纳过流保护得集成稳压电路,同样能满足产品得需要。基于上述实际意义，设计一串联串联型连续可调直流稳压负电源,其主要就是完成在输出最大电流为 500mA,稳压洗漱小雨0、05 得同时要求电流具有扩展，电路具有过流保护功能得情况下,调节电位器,使输出电压在 1、5-10V 之间连续可调。经过一系列得分析,准备，通过 Multis ｉｍ仿真软件及实际焊接与调试来。除了在布局与焊接美观方面之外，设计得电路基本符合设计要求。关键词:直流 稳压 变压 过流保护 电压可调目录第一章 设计要求 ················································1第二章 方案设计原理及比较 ······································22、1 设计方案 ··········································22、2 方案比较 ············································４第三章 单元电路分析与设计 ······································53、1 电路设计原理 ········································53、2 单元模块 ············································53.2.１ 电源变压器 ····································５ ３.２.２ 整流电路 ····································５ 3.2．3 滤波电路 ····································6 3、２、4 稳压电路 ····································7第四章 总原理图与仿真图 ·····························...
