TIDA-00637: CP and PE

Part Number: TIDA-00637
Other Parts Discussed in Thread: TIDA-010239

Hi All,

I am working on 3-Phase EV charging EVSE.

I have some query related to that, While studying the communication part of EVSE I got to know that there is PWM signal through which EV send signals for different purposes.

But here I just want to know why we short diode and resistance with EARTH(PE) terminals??

It should not be with circuit ground ???

I have also seen some videos that simulates EVSE communication they are also doing the same but I could not find the valid reason for the same.

Hello,

I would be happy to help you with your questions. First, I would like to point out that we just released a 3-phase version of this design (TIDA-010239) which the folder with user's guide, design files, and schematics can be found.

For the PE, I will need to get back to you on the reasoning. I should have an answer for you in a couple of days.

Best regards,

Errol
