Microcontroller with built in Phase Locked Loop Control

Other Parts Discussed in Thread: C2000WARE-DIGITALPOWER-SDK, CONTROLSUITE

Hello there,

I am currently working on a project for a two stage single phase solar dc to ac inverter. The output of the inverter will be grid connected, and thus must be phase locked to the grid. I am searching for a microcontroller that has phase locked loop control built in (NOT just the ability to be coded for it). Ideally, it would be some sort of "plug and play" set up. Does TI produce one of these?

We don;t have anything that has inbuilt SPLL for grid lock. In fact if you know SPLL has a lot of tweaks that are needed and are system dependent, hence a programmed approach is much better.

We have several reference designs that use SPLL for grid lock in single phase applications:

www.ti.com/.../tida-01604

you can download the software for the same from C2000WARE-DIGITALPOWER-SDK

We also have SPLL Moudles for three phase grid connected more
you can download that from controlSUITE

We have two app notes that help you implement them on C2000 MCUs
