电子负载原理, 负载效应讲的很好，很多恒压源，恒流源，恒阻源模型-The principle of electronic load, load effect speak well, a lot of the constant voltage source, constant current source, constant resistance source model

MP2307,电源电压基准芯片，电源电力电子领域常用芯片。-MP2307，a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 3A of continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast

制作电子负载，恒压、恒流、恒阻的情况。有原理图、PCB板，可以参考一下。(Make electronic load, constant pressure, constant current, constant resistance. There is a schematic diagram, PCB board, can be referred to.)

这是一个基于stm32的光伏板的程序，输入侧接光伏，输出侧接负载(This is a STM32 based photovoltaic panel program, input side photovoltaic, output side load.)
