Full textThis PhD thesis deals with multilevel inverters dedicated to high speed motors applications, used in Oil \& Gas applications. The main objective is to study a topology which enables reducing switching losses, in comparison with the conventional 3-level NPC (Neutral Point Clamped) topology. Moreover, the inverter has to provide motor input signals with a low harmonic distortion level, not to create undesired additional heating in the motor. After a study of the existing topologies, the 3-level NPP (Neutral Point Piloted) topology is chosen regarding all its benefits. Indeed, thanks to series connection of semi-conductor components, switching losses can be divided by two compared to homologous components on the NPC topology. After having compared NPC and NPP topologies in terms of waveforms and losses distribution in components, the author interest is the experimental validation of this topology. The performances reached by the NPP inverter are interesting because it enables to switch two times faster than for a NPC topology for a given current or to switch a higher current for a given switching frequency. The switching schemes of the NPP leg are studied to understand the gain obtained on this topology. In spite of the fact that switching frequency can be doubled on the NPP topology, the sinus filter can not be avoided in order to respect harmonic specification on the motor. A sinus filter with coupled inductances is introduced so that to responds the different sizing criteria

Full textThis thesis deals with continuity of service of multilevel power converters, during the failure of one of their power components. The studied converter topologies are the following, widely used in industrial applications: Neutral Point Clamped (NPC) and Neutral Point Piloted (NPP) or T-Type. First, to reduce the failure rate of the converter, an advanced control is proposed ; it increases the lifetime of the power components by minimizing the number of switchings over a period. This idea is based on the fact that a multilevel converter makes possible to generate the same output voltage level from several different switching sequences. The principle of the proposed control will be developed in a general way. Then, it is applied to the cases of 5-level "H-bridge" topologies, NPP (or T-Type) and NPC. Then, the continuity of service in nominal mode is studied for a 5 level "H-brige" NPP (or T-Type) converter, when an open circuit failure occurs on a power component. We first propose a fault diagnosis, consisting in a fault detection step, followed by the location of the faulty component. Then, an original fault-tolerant converter topology will ensure the continuity of service of the system, by modifying the control according to the localized faulty component. Reconfigurable digital electronic architectures based on Field Programmable Gate Array (FPGA) components will be dedicated to the diagnosis and the reconfiguration of the control; they will perform high temporal performances. All the results presented in this paper are validated by modeling and simulation. Then, they are experimentally validated on a test bench

Full textGiven the importance of power converter safety operation in several fields (electric traction, renewable energy, etc ..), it is necessary to examine availability of these systems in the case of malfunction of an IGBT module, a converter leg or a phase machine. Thus, it is essential to develop new hardware architectures and software controls capable of operating at significant power after fault occurence. This thesis deals with a new multilevel fault tolerant hybrid topology. It consists on adding to a 3-phase 3-level NPC (Neutral Point Clamped) inverter, a fourth 3-level FC (Flying Cap) leg. New techniques of fault tolerance parts, namely detection, isolation, reconfiguration and system control during post fault mode, are proposed, analyzed and validated with a 15kW experimental converter prototype

Full textThis work was performed in the frame of collaboration between the Laboratory on Plasma and Energy Conversion (LAPLACE), University of Toulouse, and the Second University of Naples (SUN). This work was supported by Rongxin Power Electronic Company (China) and concerns the use of multilevel converters in High Voltage Direct Current (HVDC) transmission. For more than one hundred years, the generation, the transmission, distribution and uses of electrical energy were principally based on AC systems. HVDC systems were considered some 50 years ago for technical and economic reasons. Nowadays, it is well known that HVDC is more convenient than AC for overhead transmission lines from 800 - 1000 km long. This break-even distance decreases up to 50 km for underground or submarine cables. Over the twenty-first century, HVDC transmissions will be a key point in green electric energy development. Due to the limitation in current capability of semiconductors and electrical cables, high power applications require high voltage converters. Thanks to the development of high voltage semiconductor devices, it is now possible to achieve high power converters for AC/DC conversion in the GW power range. For several years, multilevel voltage source converters allow working at high voltage level and draw a quasi-sinusoidal voltage waveform. Classical multilevel topologies such as NPC and Flying Capacitor VSIs were introduced twenty years ago and are nowadays widely used in Medium Power applications such as traction drives. In the scope of High Voltage AC/DC converters, the Modular Multilevel Converter (MMC), proposed ten years ago by Professor R. Marquardt from the University of Munich (Germany), appeared particularly interesting for HVDC transmissions. On the base of the MMC principle, this thesis considers different topologies of elementary cells which make the High Voltage AC/DC converter more flexible and easy suitable respect to different voltage and current levels. The document is organized as follow. Firstly, HVDC power systems are introduced. Conventional configurations of Current Source Converters (CSCs) and Voltage Source Converters (VSCs) are shown. The most attractive topologies for VSC-HVDC systems are analyzed. The operating principle of the MMC is presented and the sizing of reactive devices is developed by considering an open loop and a closed loop control. Different topologies of elementary cells offer various properties in current or voltage reversibility on the DC side. To compare the different topologies, an analytical approach on the power losses evaluation is achieved which made the calculation very fast and direct. A HVDC link to connect an off-shore wind farm platform is considered as a case study. The nominal power level is 100 MW with a DC voltage of 160 kV. The MMC is rated considering press-packed IGBT and IGCT devices. Simulations validate the calculations and also allow analyzing fault conditions. The study is carried out by considering a classical PWM control with an interleaving of the cells. In order to validate calculation and the simulation results, a 10kW three-phase prototype was built. It includes 18 commutation cells and its control system is based on a DSP-FGPA platform
