3 phase sinewave with Renewable Energy Kit

Omer Peleg

Hi.   I was wondering if anyone has modified code to change the Renewable Energy Dev board to 3 phase output.   The datasheet specifies that it is relatively simple to do so, but I am finding it a bit difficult.

I noticed there is a 3 phase sine generator in the Sgen library.   Would this be the direction to go in?  Is there an existing C2000 example using this?

Thanks,

Omer Peleg

    Also, would it be possible to implement this with the EPWM phase register.  For example, EPWM1 phase would be disabled and EPWM2 and 3 would sync In Phase up and Phase down?

     

    Thanks

    I believe the power device (IPM) used in that kit offers three phase inverter solution and therefore the renewable kit should be able to provide three phase output ... check out any three phase V/Hz solution to get the idea on how to generate a three phase voltage output. By the way, the output filter will also need to be three phase ... I believe the kit proivdes filter for a single phase solution. You will have to add output filter for all three phases.

    The phase register is to generate phase difference between two PWM outputs ... I believe you are asking for a phase difference between two output voltages and if that is the case then waveform needs to be generated with appropriate phase difference ... chack out any three phase V/Hz solution or waveform generation library on various implementations.

    Thanks.  I just got it to work.  I had already purchased the filter components for the other two phases.  I replaced the sgti1c.asm  file with sgti3c.asm, then added functions for sgen3.out1, sgen3.out2, and sgen3.out3.

     

    Thanks for your help.

    Hi!

    I have the same problem when I try to do the set up to make the all 3 phases running together. 

    I´d like you to explan me, if it is posible, what changes did you make to solve the problem. I have to connect a triphasic engine, so it´s basic to my project.

    Did you change anything in the board?

    I´m working with simulink, and the other 2 phases work fine, but when I try to connect all together, an error becames. 

    So, if you solved that problem in C++ code, please, tell me what code did you use, and at least, I can use it to find a way to solve my problem

    Thank you in advanced!

    It's been a while since I've worked on that project, but I still have the source code if you want me to send it to you, give me your email.   Also, you need to get the caps and inductors for the output filter for the 2nd and 3rd phases.   You can see that I wrote what I did in the previous post.

    Hi...

    I am also looking for 3 phase sine wave generation solution.

    Can any one help me out by telling me from where to start and which library to use.

     I have looked in digital motor control library and solution but didnt understand which code to use and what changes need to be done.

    As you got solution for this can you help me out.

    my ID is bhuvankanade12@gmail.com.

    Thanks in advance.
