Passivity Based Hybrid Controller of Dual Euler Lagrange Model of Three-Level Three-Phase Neutral Point Clamped Voltage Source Rectifier

Abstract:

The PBHC (Passivity Based Hybrid Controller, PBHC) with damping injection and neutral point potential balance was based on a dual-EL (Euler Lagrange, EL) model of three-level three-phase dual load NPC (Neutral Point Clamped, NPC) VSR (Voltage Source Rectifier, VSR) in dq reference frame. The simulation results from Matlab/Simulink show that the proposed control strategy has excellent performances: at the AC side, the THD (Total Harmonious Distortion, THD) is less than 5%, the PF (Power Factor, PF) is higher than 98%; at the DC side, the output voltage is able to track the desired voltage quickly, the capacitors votages are equal.
