Non-Uniform Heating Condition Effects in Microchannels of the MTPV Systems

Applied Mechanics and Materials, 2013
Heat transfer and fluid flow in the microchannel cooling passages of plane cell type MTPV systems are numerically investigated. The Finite Volume method is adopted for the governing equations discretization; The SIMPLE method is applied to deal with the linkage between pressure and velocities.

Numerical Study of Heat Transfer Enhancement in Microchannels of the MTPV Systems

Applied Mechanics and Materials, 2013
Heat transfer and fluid flow in the microchannel cooling passages with three different types of the MTPV systems are numerically investigated. The heat transfer characteristics and thermal performance of the microchannels are analyzed using different Reynolds numbers and hydraulic diameters.

An Effective Flux Weakening Control of a SyRM Drive Including MTPV Operation

IEEE Transactions on Industry Applications, 2019
A synchronous reluctance motor drive exhibits an inherent unlimited speed range capability; in fact, the maximum speed of this kind of machine is bounded only by mechanical limits. In order to exploit this peculiar characteristic of the drive while assuring the lowest power losses, a proper control algorithm has to be used.

Spectral analysis of various radiation materials of micro-burner in MTPV system

Proceedings of the 2013 International Conference on Advanced Mechatronic Systems, 2013
In order to choose the appropriate radiation material as the material of Micro-burner in the MTPV systems (Micro Thermophotovoltaic system), and make heat radiation wave of these materials meet to the wavelength of GaSb PV cells band gap as much as possible, radiation experiments of micro-burner were investigated with different radiation material in ...

Torque and Flux Weakening Control with MTPV for Interior Permanent Magnet Synchronous Motor

2016 IEEE Vehicle Power and Propulsion Conference (VPPC), 2016
This paper proposes an improved stator flux control algorithm based on the torque feedforward control technique for interior permanent magnet synchronous motor (IPMSM). The proposed flux linkage control algorithm can prevent the d and q- axis voltages from saturation and improve the dynamic behavior.

Quantitative analysis of combustor length with GM (1, 1) model for MTPV system

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
Micro combustion chamber is the core part of the MTPV power system. But the size of the combustor always is determined by the experience. In the article, we attempt to predict the size of Micro combustion chamber according to the temperature distribution trend of wall with GM (1, 1) model of the grey theory system.

Infinite speed drives control with MTPA and MTPV for interior permanent magnet synchronous motor

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
The paper presents infinite speed drives with both maximum torque per amp control and maximum torque per volt control for interior permanent magnet synchronous motor. The presented method controls infinite speed drives MTPA before flux weakening occurs.

Analytical solutions for the optimal reference currents for MTPC/MTPA, MTPV and MTPF control of anisotropic synchronous machines

2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017
Analytical solutions for the optimal current references during maximum torque per current (MTPC; or maximum torque per Ampere (MTPA)), maximum torque per voltage (MTPV) and maximum torque per flux (MTPF) operation of anisotropic synchronous machines with non-negligible stator resistance and mutual inductance are presented.
