I have been following your posts with a lot of interest.  I was sorry to see your post a few weeks ago that said you were on hold until spring.  Happy to see you were able to move indoors and continue your efforts.  It looks like you are making good progress.  Thanks for sharing your project.

Hi, thanks. I am spending the winter fabricating the DC to DC step-down converter. This project is showing a lot of potential, I will continue working on it in the spring. Thanks again.

High voltage, low current. Next I have to add a bridge rectifier and a Buck converter.

Interesting, Could you use that 200 volts to spike the battery when it is between pulse times of the wiper motor?
If that's too high dump the cap before it gets there ,multiple dumps?
Thanks for sharing.

Hi, it seems possible but the project goal is to use a Buck converter to converter a high voltage with low current to a lower voltage with higher current. This will reduce the (I square R) loss at the stator when the duty cycle is set below 50% .

Big swing5 needs some fine tuning.
