C2000 Software Frequency Response Analyzer (SFRA) Library and Compensation Designer in SDK Framework

The Software Frequency Response Analyzer (SFRA) is a software library that enables developers to quickly measure the frequency response of their digital power converter. The SFRA library contains software functions that inject a frequency into the control loop and measure the response of the system using the C2000 MCUs’ on-chip analog to digital converter (ADC). This process provides the plant frequency response characteristics, the open loop gain frequency response and the closed loop frequency response of the closed loop system. This user's guide explains the software interface of the library and lists the steps needed to integrate the library into a project. The process to run the example project for the SFRA is also documented in this user's guide.
