Introduction
The
reference design represents a complete solution for high-power, three-phase active front end (AFE)
rectifier applications based on the three-level Vienna topology.
This reference design topology is mostly used for DC fast charging applications related to industrial and electric vehicles.
It features full digital control. The embedded
mixed-signal high-performance microcontroller provides the
full control of the power factor (PF), the DC voltage, and the auxiliary task to manage the protections and the soft start-up
procedure.
The high-bandwidth continuous conduction mode (CCM) current regulation allows the maximum power quality in terms of total
harmonic distortion (THD) and power factor (PF).
