摘　　要：当今社会科学技术不断变化发展,人们在日常生活、学习中已离不开电气和电子设备,而这些电子设备的核心就是电源模块.UCC3802是一种电流型脉冲宽度调制(Pulse Width Modulation,PWM)控制芯片,电源设计上对它的依赖也在逐步增强,对UCC3802的成效和平稳性等各种目标的条件也在不断增加.为了将高稳定直流稳压UCC3802正式应用到稳压电路中,设计了一系列的相应变换、整流以及过滤处理电路,从而使其最后变成稳定工作的直流UCC3802.Today's society is constantly changing and developing in science and technology,and people have become inseparable from electrical and electronic equipment in their daily lives and studies,and the core of these electronic devices is the power supply module.UCC3802 is a current type Pulse Width Modulation(PWM)control chip,and the reliance on it in power supply design is gradually growing,and the conditions for various objectives such as effectiveness and smoothness of UCC3802 are also increasing.To formalize the high stability DC voltage regulator UCC3802 into a voltage regulator circuit,a series of corresponding conversion,rectification,and filtering processes need to be made so that it finally becomes a stable operating DC UCC3802.
