wondering how difficult to modify the above demo (22kW AFE) to be able to modify the inverter to 3 phase grid interactive from the exist one phase design that currently will just power a resistive load and a lower power level? Also , the software file is not readable in a text program, what is needed to look at the code?

    For changing to a 3-phase grid interactive inverter, you can reuse the existing 3 phase PFC closed loop code for the 3-phase grid-tied control, but you will need to change some logic in the state machine code and some limiter ranges in DC-link Voltage closed loop controller. In addition, you need to add island detection code for the grid-tied inverting mode. the 3-phase inverter also can support a power level of 22kW.

    If you need the source code files, you can request them on the web page of the corresponding reference design, as show in following.
