This paper presents an improved modulation strategy for an LLC - type resonant converter in a solar application. Neither frequency- nor phase-shift-modulation alone is used, but a new hybrid modulation technique depending on a resonant current zero-crossing. Control can be implemented using only one parameter ton while supporting soft-switching. Furthermore, this paper introduces an optimized design...
The present work deals with the technology transfer from basic research on the microwave-assisted heterogeneous gas-phase catalysis into pilot plant scale. This enables a direct comparison of the novel microwave-assisted catalysis technology with conventional heating systems by means of ohmic losses. The work is focused on the technology and not on the catalyst material, which represents only one...
The paper proposes a study of synchronization capability of line-start permanent magnet synchronous motor with small saliency ratio and very high cage resistance. The exemplified method is for a motor with the rated power of 3.5 kW, the synchronous speed of 3000 rpm, and the saliency ratio of 1.08.
