Model predictive control of four-leg three-level flying capacitor converter: influence of model parameter mismatch

Antoniewicz K., Rafal K., Jasinski M.

Power Electronics and Drives

2018

Vol. 3 (38), No. 1

1--9

This paper presents a control method for a four-leg three-level flying capacitor converter (FCC) operating as a shunt active power filter (SAPF), based on model predictive control with finite number of control states (FS-MPC). Current control and capacitor voltage balancing are described. Influence of the mismatch of the inductive filter model parameters on the current control precision is analysed. Results are supported by the experimental waveforms obtained with a 10kVA set-up.

Model predictive current control method for four-leg three-level converter operating as shunt active power filter and grid connected inverter

Antoniewicz K., Rafal K.

Bulletin of the Polish Academy of Sciences. Technical Sciences

2017

Vol. 65, nr 5

This paper presents model predictive control (MPC) with a finite control states set (FS) for three-level four-leg flying capacitor (FCC) converter. Principles of control method are presented and flying capacitor voltages control method is discussed. Experimental results of converter operating as a shunt active power filter (SAPF) and grid connected inverter (GCI) are shown.
