2018年湖北省电赛程序,前面的DC-AC稳压和变频能工作,但是变频的时候会随机性的导致MCU跑飞,尚不清楚原因。输出的AC通过变压器连接后面的AC-DC和boost电路。

stm32-dc-ac-ac-dc's Introduction

STM32-DC-AC-AC-DC

2018年湖北省电赛程序,前部分DC-AC稳压和变频能工作,但是变频的时候会小概率随机性的导致MCU跑飞,尚不清楚原因,希望有人能帮忙看看,但应该不是内存的非法访问,所以当时亡羊补牢加了看门狗。我变频是通过MCU计算,改变SPWM数组来实现的,没有改变PWM的频率。

输出的AC通过变压器连接后面的AC-DC和boost电路,AC-DC采用全桥电路实现的,一开始是准备用有源功率因数校正PAFC,可惜到比赛第三天没把他完成,第四天变为最简单的全桥整流了。输出的DC经过boost电路稳压输出,但是一块在比赛当天没有时间调试了,所以并不能稳压输出。
