CODE EXAMPLES
FOR B-Box RCP and B-Board PRO
This page introduces useful code examples for the B-Box RCP and B-Board PRO controllers. Most of them now directly link to our knowledge base, which gathers numerous technical articles as well as product-related documentation.
For those who are working with the good old BoomBox, hardware rev. 2.0, code examples can be found on the dedicated page.
Three-phase voltage source inverter
This example generates three-phase alternating currents from a voltage source inverter in an open-loop manner. It can serve as an introduction to imperix control and power products, but also as a reference model for performing a first set of tests on new equipment, or simply as a control code for a grid-forming inverter. The example provides reference files using the ACG SDK library for Simulink.
