TL;DR: A robust control strategy of the quasi-resonant circuit operation with an inverter output voltage dv/dt limitation has been achieved and a PQRDCLI analysis with the aid of simulations and experimental tests is carried out.
Abstract: In this paper, a new scheme of a parallel quasi-resonant dc-link inverter (PQRDCLI) for electrical drive applications is described. Principles of the soft-switching inverter operation for bidirectional energy transmission are presented. A PQRDCLI analysis with the aid of simulations and experimental tests is carried out. The circuit features relatively simple topological structure and moderate overcurrent stress of components. A robust control strategy of the quasi-resonant circuit operation with an inverter output voltage dv/dt limitation has been achieved.

TL;DR: In this article, the authors illustrate how to account for all parasitic due to the layout of a power converter (inductive and capacitive), in order to forecast electromagnetic interferences (EMI).
Abstract: This paper illustrates how to account for all parasitic due to the layout of a power converter (inductive and capacitive), in order to forecast electromagnetic interferences (EMI). The method is generic, and is validated here in the simple example of a DC-DC converter, realized on different technologies: insulated metal substrate (IMS), printed circuit board (PCB). In addition, several layouts aspects will be investigated. Conclusions are given on the influence of layout and all other components on EMI.

TL;DR: In this article, a fault diagnosis in a voltage-fed inverter for induction motor drives has been conducted with the aid of the TCAD circuit simulator and the experimental laboratory unit.
Abstract: A research on fault diagnosis in a voltage-fed inverter for induction motor drives has been conducted with the aid of the TCAD circuit simulator and the experimental laboratory unit. Classification and a base knowledge of failures has been derived from the frequency conversion chain of the decomposed power system. Sensor available variables are considered as stator currents and voltage across the filter capacitor. A method of fault diagnosis has been proposed based on current space vector trace inspection combined with the Fourier series processing. Simulation and experimental results on fault diagnosis during operation of 2.2 kW induction motor drive are given.

TL;DR: In this paper, a parallel quasi-resonant dc-link inverter (PQRDCLI) was proposed to limit high-frequency common-mode voltage and bearing currents.
Abstract: In this article, a concept of separation of an inverter-fed induction motor drive from its mains supply by two transistor switches inserted in the dc-link circuit is re-examined based on the proposed parallel quasi-resonant dc-link inverter (PQRDCLI). The objective of the article is to show an advantage of the proposed topology in limiting high-frequency common-mode voltage and bearing currents. In the laboratory setup, an induction machine was equipped with hybrid ceramic bearings and an insulated clutch to measure the shaft-to-frame bearing voltage and the shaft-grounding current. Experimental tests of the PQRDCLI confirm significant reduction of common-mode voltage and shaft-to-frame bearing voltage at dc-link zero voltage notches. By controlling the output voltage slopes, the shaft-grounding brush current and the ground leakage current are also reduced. The efficiency measurement and evaluation of the proposed topology, as compared with a two-level hard switched inverter, reveal comparable efficiency of around 95% and indicate loss distributions in both inverters.

TL;DR: This paper aims at providing a review of the major techniques used for the induction motor parameter estimation, illustrated throughout with experimental and simulation examples related to various parameter estimation techniques.
Abstract: An induction motor is the most frequently used electric machine in high-performance drive applications. Control schemes of such drives require an exact knowledge of at least some of the induction motor parameters. Any mismatch between the parameter values used within the controller and actual parameter values in the motor leads to a deterioration in the drive performance. Numerous methods for induction machine on-line and off-line parameter estimation have been developed exclusively for application in high-performance drives. This paper aims at providing a review of the major techniques used for the induction motor parameter estimation. The paper is illustrated throughout with experimental and simulation examples related to various parameter estimation techniques.

TL;DR: Suggested in this paper is also an alternative solution for the normalization of DC components, which is easier interpreted and simpler to implement.
Abstract: A novel method is presented for the detection and isolation of open-transistor faults in voltage-source inverters feeding AC motors. The method is an extension of the normalized DC-components method. The normalized average currents are combined with additional diagnostic variables which convey information about the percentage of time spent by the phase currents in the near-zero zone. The combined diagnostic signals permit much more robust diagnostics of single-transistor faults and make feasible the diagnostics of multiple-transistor faults. Suggested in this paper is also an alternative solution for the normalization of DC components, which is easier interpreted and simpler to implement.
