Inductor Compensation in Three Phase PFC Control with Decoupling the Input Voltage and Bus Voltage

MATEC Web of Conferences, 2016
As the nonlinear structure of the boost ac/dc topology, the PFC is difficult to be controlled. The average state space theory has revealed that the choke current is determined by duty-ratio coupled with input voltage and bus voltage, which makes the high-
