A hysteresis current control PWM for PV tied Z-source NPC-MLI fed induction motor with neutral point balancing

Photo-voltaic (PV) tied Z-source Neutral-point clamped NPC-MLI (Z-NPC-MLI) is used in solar grid connected applications due to its improved performance related conservative inverters single stage power conversion. Though the Z source adaptation accepted technology, need for appropriate controller meet out grid/standalone requirements becoming necessary. The space vector pulse width modulation (SVPWM) strategy a prominent technique NPC-MLIs their voltage selection opportunity. current (CC) based SVPWM not attempted, which most essential consideration inverter provide low harmonic distortion, high quality current. With all this aim, paper presents PV Z-NPC-MLI system with unique hysteresis control (HSVM) neutral point (NP) balancing control. simulation results are confirmed feasibility and reliability of proposed CC tie Z- Source MLI.
