3.5.2 Vienna Rectifier-Based Three Phase Power Factor Correction

Vienna rectifier power topology is used in high power three phase power factor (AC-DC) applications, such as off board EV chargers and telecom rectifiers. TIDM-1000 illustrates a method to control the power stage using C2000™ microcontrollers (MCUs). TIDM-1000 Benchmarking shows early benchmarking results on Lab four (closed voltage loop with inner current loop and midpoint voltage balancing). The cycles are measured inside the ISR from start to finish. The results show the F29x achieves twice (in cycles) the performance of the C28 CPU.
