Interior permanent magnet synchronous motors (IPMSMs) are currently widely utilized as traction motors. The permanent magnets used in IPMSMs are an important factor; thus, high-coercivity permanent magnets with lesser rare-earth elements are in development. This paper proposes two modified versions of double-layered IPMSMs containing a strong magnet to improve their efficiency and reduce their size...
The paper describes a compact high-voltage pulse generator for supplying the non-thermal plasma reactors for sterilizing powdered spices. Built and investigated converter generates a high voltage pulses of 35kV in amplitude and 70kW in a peak. The first part of the article presents an analytical description of Tesla transformer. Next part describes topology based on Tesla transformer with a toroidal...
The paper investigates a thermal behaviour of a DC inductor deployed in a 600 kW power converter for particle accelerators. The inductor is manufactured from electrical steel core and two magnetically coupled windings with integrated air ducts for enhanced air circulation. The thermal analysis of inductor are carried out by means of a Computational Fluid Dynamics (CFD) model and simulations. The paper...
The subject of this paper is to propose a design method of the EMI filters that allows to minimize the volume of the common-mode inductor with consideration of core saturation issues. Inductor volume depends not only on its inductance value, but also on the relationship between the filter and its environment which can saturate the magnetic material due to many parameters, especially when the filter...
DC is regarded as an attractive alternative to conventional AC technology in collection networks for large-scale wind and PV generation systems. Playing the role in the stepping up voltage and exporting the power from the individual generation units, DC/DC converters are one of the most crucial parts of the DC collector. Isolated medium-power DC/DC converters would require a medium voltage medium...
This paper presents a magnetically integrated isolated bidirectional three-port DC-DC converter (TPC) that includes an integrated dual active bridge converter (DAB) and non-isolated bidirectional DC-DC converter (NBC), each of which can be independently controlled. The proposed TPC simultaneously uses large, small, and magnetizing inductances, of which the small and magnetizing inductances are used...
In this paper the line reactor design for parallel connection of high power inverters with interleaved carriers is presented. Based on state of the art interleaving reactors configurations and based on high power requirements, design iterations are performed to detect the implementation issues. The parasitic effects are highlighted in finite element models and a new reluctance model is introduced...
Magnetic components using soft core materials are widely used in power electronic converters. The hysteresis effect of the material leads to power loss and harmonic distortion. If this effect can be modeled in system-level time-domain simulation, the performance of the magnetic component in combination with power converters can be predicted more accurately during the design phase. This work proposes...
