This paper proposes a new control method to increase cascaded multilevel inverters (CMI) efficiency at faulty condition. The influence of most probability fault on CMI with carrier based pulse width modulation (CBPWM) is investigated and the maximum output voltage is derived without elimination of faulty power cell. This method is able to produce balanced phase voltage on faulty phase. In addition proposed method can be used in the H -bridge cascaded multilevel inverter of any voltage levels. Simulation results are provided.

Frequency Modulated Raman Spectroscopy Greco, Silvio; Dal Zilio, Simone; Bek, Alpan; Lazzarino, Marco; Naumenko, Denys (2018-02-01) The coupling of plasmonic and mechanical properties at the nanoscale is of great potential for the development of next generation devices capable to detect weak forces, mass changes, minute displacements and temperature induced effects. Both the transduction of mechanical motion to the scattered light fields in term of polarization or intensity modulation and plasmon-driven mechanical oscillations have already been demonstrated. Quasi static tunable hot spots have recently been designed and applied to surfa...
PWM inverter harmonics contributions to the inverter-fed induction machine bearing fault diagnosis Akin, Bilal; Toliyat, Hamid A.; Orguner, Umut; Rayner, Mark (2007-03-01) The effects of inverter harmonics on motor current fault signatures are studied in detail in this paper. According to theory and experimentation, the fault signatures caused by the inverter harmonics are similar and comparable to those generated by the fundamental harmonic of the line current. Unlike the utility-driven motor, monitoring the current of the inverter-fed motor is considerably noisy, which can mask the fault signatures and render a wrong fault warning. Therefore, the proposed additional fault d...
Performance Evaluation and Selection of PWM Switching and Control Methods for Grid Connected Modular Multilevel Converters Ciftci, Baris; Hava, Ahmet Masum (2015-09-24) This paper focuses on the determination of suitable carrier based pulse width modulation (PWM) switching and control methods for grid connected modular multilevel converters (MMCs). Characterization of various level-shifted and phase-shifted carrier based PWM methods are provided in terms of output voltage waveforms both for N+1 and 2N+1 level output phase voltages. Carrier based PWM method based control approaches are evaluated for MMC. Performances of different control methods are evaluated and compared f...
Modelling a 7-Level Asymmetrical H-Bridge Multilevel Inverter with PS-SPWM Control KABALCI, ERSAN; ÇOLAK, İlhami; BAYINDIR, RAMAZAN; Pavlitov, Constantin (2011-09-10) Although the multilevel inverter topologics are comprehensively studied in power conversion issues, novel topologies are still being sought in order to decrease required semiconductors for same output levels that are currently obtained with classical multilevel topologies. Several studies have been reported in the literature on multilevel inverter topologies and control techniques. However, the cascaded multilevel inverter topology is one of the most widely studied topology to increase the output levels, as...
Fault Tolerant Multi-Tx/Multi-Rx Inductive Power Transfer System with a Resonator Coil Ayaz, Enes; Altun, Ogün; Polat, Hakan; Keysan, Ozan (2022-01-01) This paper presents a novel multi-transmitter (Tx) / multi-receiver (Rx) inductive power transfer system. Compared to conventional single-Tx/single-Rx systems, multi-Tx/multi-Rx topologies increase reliability and fault tolerance. However, unequal power distribution is challenging in these systems due to coupling differences, which prevents them from operating at rated power or requires over-designed modules. This study proposes the addition of a middle-stage resonator (MSR) that balances power distribution...
