Micron-gap ThermoPhotoVoltaics (MTPV) [PDF]
AIP Conference Proceedings, 2004 This paper discusses advances made in the field of Micron‐gap ThermoPhotoVoltaics (MTPV). Initial modeling has shown that MTPV may enable significant performance improvements relative to conventional far field TPV. These performance improvements include up to a 10× increase in power density, 30% to 35% fractional increase in conversion efficiency, or ...

Synchronous reluctance motor iron losses: considering machine non-linearity at MTPA, FW, and MTPV operating conditions [PDF]
IEEE Transactions on Energy Conversion, 2018 Synchronous reluctance machine has high flux density fluctuations in the iron due to the high harmonics results from the rotor anisotropy. Thus, an accurate computation of the iron losses is of paramount importance, especially during the design stage. In

Identification of five putative yeast RNA helicase genes. [PDF]
Proc Natl Acad Sci U S A, 1990 The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...

MTPV Flux-Weakening Strategy for PMSM High Speed Drive
IEEE Transactions on Industry Applications, 2018 High speed permanent magnet synchronous motors (PMSMs) are used in electric vehicles because of their intense power density. The high speed implies a significant electromotive force and requires flux weakening. The usual control algorithms realize flux weakening by adding a negative I d current component when the voltage required by the current ...
