Motor voltage feedback.

Posted on January 10, 2016 at 17:24Now that I have FOC working on the STM board and the STM ''power stage'' the next step is to move all this over to my own power stage and logic board. The CPU part can wait, so now I'm working on getting the nucleo...

Brushless Motor control with Hall sensors (sensored)

Posted on March 17, 2016 at 08:23Hi there,I have built my own circuits to drive a BLDC motor. So far I have managed to get an RC BLDC motor working quite smoothly in open loop. However my 1kW motor is not running good at all, it cgs at lows speed an...

STL62P3LLH6 Safe Operating Area correct?

Posted on March 31, 2016 at 15:28I'd like to know if the STL62P3LLH6 P-channel MOSFET's Safe Operating Area chart is correct in http://www.st.com/web/en/resource/technical/document/datasheet/DM00105886.pdfhttp://www.st.com/web/en/resource/technical/...

Major Mistake in my design

Posted on March 29, 2016 at 12:45Hi, I attached my schematic to help in my discussion.  I made a huge mistake by selecting a Linear Regulator U200: (12Vin - 5Vout).  Roughly I'm drawing about 1.5Amps, therefore my power dissipated across the IC is (...

ST1CC40 no load output voltage

Posted on March 08, 2016 at 05:48Hi, I'm trying to build a constant current LED driver using the ST1CC40. I built a prototype version and noticed that with no load attached, the entire Vin (in my case its 12V) is seen at the output. Is this normal? ...

L4984D

Posted on March 28, 2016 at 07:43Hello! I want to ask a question about chip PFC L4984D.1. Calculate the inductor according to datasheet. When the input voltage is greater than 200 volts, the inductor begins to make noise, heavily distorted input cur...
