This paper presents a model predictive controlled three-level three-phase active neutral-point-clamped (ANPC) inverter for distributing the voltage stress among the semiconductor power switches as well as balancing the neutralpoint voltage. The model predictive control (MPC) concept uses the discrete variables and effectively operates the ANPC inverter by avoiding any linear controller or modul...

This paper proposes a three-level diode clamped active impedance source inverter (AIS-TLI) based on the quasi Z-source (qZSI). Apart from having minimal components and inherent benefits of qZSIs, such as single-stage buck-boost capability, shoot-through (ST) immunity, continuity input current, proposed topology has higher boost capability excellent efficiency. In addition, bridge modulation ind...

Power electronic converters are becoming more and more popular for various industrial applications. To overcome the limitation of semiconductors current and voltage ratings in high power applications, series and parallel connection of switches is often considered an effective solution. In addition, stepped waveform in the output of inverter has better harmonic spectrum than 2-level waveform in ...

This paper intmduces the circuit and PWM control strategies of the Neutral-Point-Clamped (NPC) inverter and Cascade-Inverters with Separate DC Source (CISDS), analyzes and compares their advantages and disadvantages. A new type of Parallel Connected NPC inverter (PCNPCI) is proposed here. Based on inherited all merits of the three-level structures, only added very few components, it can produce...

<p>This paper presents a step-wise modelling of symmetrical six-phase induction machine driven by diode clamped multi-level inverter at varying rotor resistance and motor inertia. The drive process was considered in two stages. first stage the dynamic behavior when load torque 0 Nm 100 is applied varied external value (0.8 3.2) Ω with constant second showcased variations speed, electromag...
