“…Different control methods for voltage balancing and current control exist such as linear/nonlinear controllers, predictive model, fuzzy, etc [33][34][35][36][37]. Model Predictive Control or MPC uses a model of the system to predict the future behavior of the variables [24,27].One of the major advantages of the FCS-MPC compared to a traditional PI controller is the flexibility to control different variables, with constraints and additional 0278-0046 (c) 2015 IEEE.…”

Abstract-In this paper a model predictive control (MPC) has been designed and implemented on the Packed U-Cell (PUC) inverter which has one isolated DC source and one capacitor as an auxiliary DC link. The MPC is designed to regulate the capacitor voltage at the desired magnitude to have seven voltage levels at the output of the inverter. Since grid-connected application is targeted by this application, the inverter should be capable of supplying requested amount of active and reactive power at the point of common coupling (PCC) as well. Therefore, MPC should also consider the line current control in order to monitor the exchange of reactive power with the grid while injecting appropriate active power at low THD. Various experimental tests including change in DC source voltage, active power variation and operation at different power factor (PF) have been performed on a laboratory prototype to validate the good performance obtained by the proposed MPC. The dynamic performance of the controller during sudden changes in dc capacitor voltage, supply current and PF demonstrates the fast and accurate response and the superior operation of the proposed controller.

“…Among them multilevel converter such as 3-phase Neutral Point Clamped (NPC) is becoming more popular in the applications such as grid-tied. Because it outputs more voltage level with less switching losses [4] [5]. These merits of NPC converter make it guaranteed to exchange the electrical energy at low to medium voltage with lower current, less paralleled devices, and reduce size of filter in correlation with two-level converter [6] [7].…”

Abstract-A multilevel boost PFC (Power Factor Correction) rectifier is presented in this paper controlled by cascaded controller and multicarrier pulse width modulation technique. The presented topology has less active semiconductor switches compared to similar ones reducing the number of required gate drives that would shrink the manufactured box significantly. A simple controller has been implemented on the studied converter to generate a constant voltage at the output while generating a five-level voltage waveform at the input without connecting the load to the neutral point of the DC bus capacitors. Multicarrier PWM technique has been used to produce switching pulses from control signal at a fixed switching frequency. Multi-level voltage waveform harmonics has been analyzed comprehensively which affects the harmonic contents of input current and the size of required filters directly. Full experimental results confirm the good dynamic performance of the proposed five-level PFC boost rectifier in delivering power from AC grid to the DC loads while correcting the power factor at the AC side as well as reducing the current harmonics remarkably.
