4. Digital control section
The STEVAL-IPFC02V1 implements mixed signal (analog/digital) control, combining the flexibility of a
programmable high end digital solution with the responsiveness and accuracy of analog componentry. The
inner current loop consists of an analog proportional-integral (PI) compensator that ensures the highest possible
bandwidth and cycle-by-cycle regulation. The outer voltage loop is performed by a digital PI controller with fast
dynamic response.
