“…In contrast to the two parameters of prediction horizon and sampling time, this parameter has no significant effect on the system stability and it only affects the transient response of the system. The choice of control horizons is important only in constrained systems and its selection is not important for unconstrained systems so that the long control horizon result in more computational volume (Santoyo-Anaya et al, 2018).

“…The state space method is used to model this converter. Dynamic elements are selected as system state variables; therefore, capacitor voltage and grid current are selected as rectifier system state variables (Santoyo-Anaya et al, 2018). With this assumption, the state equations of the system are given as follows:…”

The rectifier is one of the popular power electronic converters in industrial applications such as in the railway and power supply systems. In this paper, a three-phase controllable rectifier is considered and the continuous control set model predictive controller (CCS-MPC) is designed. By considering system dynamic response, the proper criteria to select the sampling time, prediction horizon and control horizon is proposed. By using these criteria, the tradeoff between computational burden and system performance dynamic is made. When using the CCS-MPC controller, the rectifier and grid performance such as total harmonic distribution (THD) and power factor (PF) have acceptable value. The simulation results are validated by using MATLAB/SIMULINK software.

“…Since that time the CSC has been applied to multiple type of PFC topologies: single switch PFC (diode bridge and boost converter) [38,39], interleaved [40,41], bridgeless [42,43], half-bridge [44][45][46], full-bridge [47,48] and also neutral-point clamped multi-level converter (NPC MLC) [49,50]. Several recently published papers have been devoted to different type of three-phase converter topologies operated under CSC [51][52][53] that makes evidence of CSC use in high power applications.…”

The current feedback is considered as unavoidable part of most control system driving power electronic converters. However, it is possible to eliminate the use of current sensor, if properly calculated volt-second balance is applied to input inductor. This paper describes the implementation of current sensorless control technique applied to neutral point clamped multi-level converter, where only voltage control-loop is used to stabilize internal capacitors voltage, while inductor’s current is shaped by means of current sensorless control block in both discontinuous and continuous current modes. The capacitor voltage balancing is implemented by means of delta-controller that selects alternative capacitor in respect to main switching scheme. Finally, the analytical study of proposed solution is verified with simulation results.

“…In DC high power fast chargers, usually AC/DC converter joint with a DC/DC isolated converter is suggested since it shows a better control task and also satisfies specific requirements in the relevant standards [5]. These converters are used recently as the input subsystem in most applications, thanks to their high performance in power factor (PF) and current total harmonic distortion (THD) control [6]. These days, a favourable topology for AC/DC stage is pulse width modulation (PWM) rectifier.…”

“…In order to consider the unbalance conditions in the input voltage, in [12] a feed‐forward term has been used in the d ‐axis current controller loop for VOC control and the PI controllers are tuned. In [6] a sensorless single PI controller loop has been used to control of PWM rectifier. This has been performed in ABC frame instead of the rotational d ‐ q frame, where the PI controller tuning was performed by plant average model.…”

This study focuses on considering battery one time constant model in the design of controllers of a two-stage AC/DC and DC/DC battery charger using the small-signal approach. For this aim, small-signal models of DC/DC and AC/DC converters and also the battery model are obtained. Moreover, the effect of disturbance terms are analysed to be omitted in controller loops. Simulation and experimental results of a 1 kW laboratory prototype show appropriate performance of designed controllers in tracking reference signals. Also, tuned controllers using this approach have guaranteed unity power factor and low total harmonic distortion. Furthermore, a complete charge cycle of a lithium-ion battery evaluates the performance of the converter in different constant current/voltage controlling modes. In comparison with restive model consideration, results show a more accurate model with grater damping ration and better stability characteristics.
