单相逆变器及基于STM32 SPWM生成代码

若需商业合作可私聊留VX号，博主看到后会添加的。

--------------------------------------------------------------------------------------------------------------------------

最近在做单相逆变器，用篇文章来记录。

主电路采用H桥，使用IR2104半桥驱动内置630ns死区，上管采用自举电容浮地驱动

SPWM采用STM32F103C8T6产生两路互补的30K Hz 的SPWM。

LC滤波器的截止频率约为开关频率的1/10~1/5，我选的是30KHz的开关频率，则LC滤波器的截止频率约为3K，即截止频率越小越好。

电流检测采样ACS712，该芯片可以直接测DC电流和AC电流，缺点就是温漂较大，测量精度较小。适合于对精度要求不高的场合。

电压检测利用全桥整流，后经电压分压，稳压管是为了保护单片机AD转换输入口的电压，将其钳位在3V以下。

SPWM产生使用单片机查表产生。

正弦表值

正弦表计算时要注意ARR寄存器的最大值和最小值。

由于单片机的自动重装载寄存器ARR是无符号二进制，所以要将正弦表值在0.5ARR的偏置。

当占空比大于0.5输出为正，当占空比小于0.5输出为负。

PWM的开关频率要大于15KHz，我用的是30KHz

输出正弦波的频率 $f_{sin}=\frac{f_{pwm}}{N}$

其中N是正弦波一周期内采样数，也即正弦表数组中数的总数。

通过定时器中断来更新比较寄存器CCR的值，以使PWM的脉宽按正弦规律变化。

如果需要调压，可以将正弦表值乘以一小于1.0的调压系数，需要注意的是单片机的正弦表是按单极性计算出来的，所以调压在程序上要分两步。

附上timer部分代码
