3 phase motor control

Other Parts Discussed in Thread: CONTROLSUITE

Dear All,

     I want to write software for 3 phase inverter. All source code available and online documents specify 3 phase motor control.

In case of 3 phase motor control outer control loop is flux or rotation of motor control loop which generates reference current id ref & iq ref for inner current loop.

What will be changes in case i want to develop code for 3 phase inverter.

1. 3 phase inverter inner loop will be current and out will be voltage loop ?

2. If i want to connect output of invertre to mains then will be there any change control loop blocks in termes of voltage and current loop ?

 Kindly provide any documents if available .

Thank You in advance.

    Hi Bhuvaneshwar,

    Your post is being moved to the C2000 forum. They are more knowledgeable about the code.

    We do not have three phase voltage mode control or current mode control examples ready for you to use,

    However if you download controlSUITE you will get SolarLibrary controlSUITE/libs/app_libs/solar/vx/.. and you will find all the necessary blocks needed for this application like park, clark, ipark and iclark transforms and also the three phase software phase locked loop which is essential for grid connected applications. An application note about how the SPLL is designed is found here:

    www.ti.com/.../sprabt4a.pdf

    The software blocks are tested on fixed point, floating point and CLA architecture and are ready to use.. how you can connect them for construction of control loops is relatively straight forward and there are multiple papers you can consult online..

    Dear Manish,

        Thank you for your prompt reply.

    Yes I have gone through all those sample code and documents.

    My qestion is about control blocks only.

    In case of 3 phase inverter what will be inner control loop and outer control loop ?

    How to decide that inner will be current control loop and outer will voltage control loop ?

    Thank You
