从电源板MB459迁移到IHM023V2发现STM32F10X-128K-EVAL的连接器引脚是相同的

全部 - 为了省去一点麻烦，这是我将现有的电源板（由ST停产）迁移到新的IHM023V2电源板时发现的：

1）STM32F10X-128K-EVAL的连接器引脚是相同的。
2）但是，下部IGBT驱动信号的极性反转。这需要软件改变timer1输出的极性。
3）电气设计存在缺陷：电源总线需要在每个桥臂处进行高频去耦。我在3个支路的每一个上使用了一个1uF，200v的陶瓷盖（上部的漏极到下部的源极;在电路板的背面，正好在引脚上。你可以在更高的电压下使用更低的值，但它需要高频去耦。不这样做会导致严重的EMI问题。
4）W16的跳线文档错误。通过观察PCB上的铜是显而易见的。该跳线控制霍尔传感器或编码器的电源。

除此之外它似乎工作。

All - to save you a bit of trouble, here is what I found when I migrated my existing power board (discontinued by ST) to the new IHM023V2 power board:

1) The connector pin-out to the STM32F10X-128K-EVAL is identical.
2) However, the polarity of the lower IGBT drive signals is inverted.  This requires a software change to the polarity of the timer1 outputs.
3) There is a flaw in the electrical design: the power bus requires high frequency decoupling at each of the bridge legs.  I used a 1uF, 200v ceramic cap across each of the 3 legs (drain of upper to source of lower; on the back of the board, right on the pins.  You may be able to go with a lower value at higher voltage but it NEEDs high frequency decoupling.  Not doing this will cause major EMI headaches.
4) The jumper documentation for W16 is wrong.  It is obvious by looking at the copper on the PCB.  This jumper controls the power to Hall sensors or encoder.

Other than that it seems to work.
