Abstract

A methodology for controlling three phase PFC Sepic converter is presented, and behavior of the system is evaluated. The converter is connected in delta at the input and parallel at the output side, and is controlled by variable hysteresis current control method. By this approach, the current drawn by each of the individual converters is controlled to be in phase with its own input voltage. Detailed design criteria for the power and control stages of the single-phase Sepic converter are presented and effects of this method on THD are verified.
