Differential Flatness-Based Control of Current/Voltage Stabilization for a Single-Phase PFC with Multiphase Interleaved Boost Converters

Abstract : This paper presents an original control law for a single-phase PFC with multiphase interleaved boost converter for high power applications. This kind of system is a nonlinear behavior. Classically, to control the current and voltage in the converter, a linearized technique is often used to study the stability and to select the controller parameters of the nonlinear converter. In this paper, a nonlinear-control algorithm based on the diffential flatness approach is proposed. Utilizing the flatness theory, we propose simple solutions to the system performance and stabilization problems. To authenticate the proposed method, a prototype single-phase PFC with two-boost converters (1-kW, 360-Vdc is realized in the renewable energy research centre. The proposed control law is implemented by digital estimation in a dSPACE 1104 controller card. Experimental results in the laboratory validate the exceptional control structure.
