**基于HT32F52352的智能电子负载开源，合泰杯作品开源，含原理图、PCB、程序源码、作品报告。**

2023第十届广东省大学生合泰杯单片机应用设计竞赛三等奖作品。

用一个月时间（而且课多没啥时间弄）赶工做出来的， **做得很一般，勿喷** 。

## 什么是电子负载

电子负载是一种电子设备，用于模拟真实负载环境，以测试电源或电子电路的性能。比起使用大功率可调电阻或者电炉丝等传统的无源负载，电子负载具有参数可调，使用方便等诸多优势。无论是专业的电子工程项目开发还是业余的电子爱好者，电子负载仪都是必备的设备之一。

电子负载从测试电源的种类来分可以分为交流电子负载和直流电子负载。从功能上划分常见的有恒流、恒压、恒阻、恒功率四种类型。因为我们常见的大多数电源都是恒压直流电源。测试这类电源时，主要测试的是其电流输出能力。所以大多数的应用场景中，直流恒流电子负载是最为常见的类型。而电子负载从控制方式上划分则又可以分为数控和模拟两种类型。相较于使用纯模拟电路控制的电子负载，数控电子负载使用数字控制，在参数调节上更为直观，而且功能丰富、扩充简单，还可以方便的实现测试的自动化。

## 项目简介

本作品采用 HT32F52352 合泰单片机作为主控芯片设计的电子负载，供电方式由18650锂电池供电，方便携带。

控制方式为通过单片机输出PWM波到低通滤波电路滤出一个较为稳定的直流电压（通过PWM+低通滤波实现DAC的功能）作为参考电压给到运放与电流/电压采样放大后的电压做比较，运放输出控制MOS管，从而实现恒压/恒流。

触控屏用的是陶晶驰的2.8寸串口屏，型号为：TJC3224T028\_011R。

## 实物图

当时没拍多少照片，就找到这两张了，可以去看看演示视频。
