This paper presents a multi-port isolated DC-DC converter for DC applications. A three-port structure is presented, characterized with full bidirectional power flow and simple control. Galvanic isolation is achieved by means of a multi-winding medium frequ ...
Stepper motors are a very convenient and economical solution for accurate positioning applications where long lifetime and low wear are required. Their particularly simple open-loop operation reduces the number of control components to a minimum. However, ...
Energy saving becomes more and more important. Therefore different improvements have been made in motor design, electronic devices and software in order to increase the overall efficiency of electronic motor drives. Permanent Magnet Synchronous Motors (PMS ...
The basic idea of the project (run in collaboration with a Swiss company) is to design a flexible winding, which will 'replace' the classical slotless BLDC motor winding. The new winding should be thermally and mechanically improved compared to the classic ...
We report a facile synthesis of single-phase, nanocrystalline macroporous chromium nitride and chromium titanium nitride with an inverse opal morphology. The material is characterized using XRD, SEM, HR-TEM/STEM, TGA and XPS. Interconversion of macroporous ...
This paper presents an eigenvalues analysis method for an induction machine model based on phase variables a, b, c. This approach is validated by comparison with ad, q approach and applied to a variable speed pump-turbine unit using a simplified model of t ...
Increasing material costs and emerging applications have steered research trends towards compacter and therefore faster drives. The arising challenges of miniaturization have made contactless magnetic levitation increasingly attractive, which offer practic ...
Reliable simulations of electromagnetic interference in motor drive power electronic systems ask for accurate high-frequency motor models. A methodology for creating frequency dependent behavioral circuit models of ac electrical motors is presented in this ...
This paper presents a vector current control method tailored for single-phase voltage source converters. In order to imitate the behavior of a three-phase system, the Fictive Axis Emulation (FAE) concept is employed. The latter is able to synthesize the ro ...
The paper presents an automated FPGA-based real-time electromagnetic transients simulator for power electronics and power systems applications. The simulator features an automated procedure enabling its straightforward applications to different topologies ...
