概要
This firmware provides control for high power three-phase AC/DC rectifier applications based on Vienna topology featuring mixed-signal control. It runs on the STNRG388A controller providing digital output voltage regulation, while analog circuitry manages CCM current regulation to provide high power quality, with low THD and high PF.
The firmware provides an environment to configure output voltage, control parameters and protection thresholds. The digital controller uses the operating parameters to determine appropriate reference signals for the analog circuitry and event-driven state machine (SMED) to generate modulation signals for PFC output control.
