Abstract :
A nonlinear average current control method using only dc-rail current for three-phase power-factor-corrected (PFC) converters was introduced recently. This paper discusses the effects of dead-time, sector synchronization, input voltage harmonic distortion and sensing delay on its control performance. A dead-time compensation scheme without additional sensing requirement that is suitable to the nonlinear average current control is presented. Based on the analysis of the current control performance considering effects of different factors, design guidelines are provided for practical implementation of the control method. Measurement and simulation results are included to support the conclusions.
