AC-DC converters that are used to generate DC voltage based on a single-phase AC power supply need to suppress the harmonics of the input current. For this, power factor correction (PFC) converters are generally used in single-phase AC applications, and various studies have been conducted. In previous studies, model predictive control (MPC) has been used to reduce grid current harmonics resulting from high responsiveness however, it was applied only to the current controller. In this paper, we propose a configuration in which MPC is applied to DC voltage control and reactor current control. Furthermore, we propose a compensation method that uses modeling errors to handle variations in the output power of the converters.
