A CFD Study of Thermodynamics and Efficiency Metrics in a Hydrogen-Fueled Micro Planar Combustor Housing Dual Heat-Recirculating Cylindrical Combustors for MTPV Applications

Processes
The micro combustor is the energy source of micro-thermophotovoltaic systems; thus, optimizing its design is one of the key parameters that lead to an increase in output energy. Therefore, to enhance the system’s overall efficiency, this numerical work introduces a new design configuration for parallel-flow (PF) and counter-flow (CF) hydrogen-fueled ...

Development of FW and MTPV Control for SynRM via Feedforward Voltage Angle Control

IEEE/ASME Transactions on Mechatronics, 2021
In order to develop a wide speed range operation of synchronous reluctance motor (SynRM) drive system for constant torque, constant power and reduced power regions, an extended speed control (ESC) with maximum efficiency (ME), flux weakening (FW), and maximum torque per voltage (MTPV) is proposed in this study. Firstly, a conventional FW control system

A Virtual Signal Injection Based MTPV Control for IPMSM

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
A control method for accurately tracking the maximum torque per voltage (MTPV) operation points of interior permanent magnet synchronous motors (IPMSM) is proposed in this paper. A square-wave signal is mathematically injected into the flux linkage angle to realize accurate tracking of MTPV operation points utilizing the inherent characteristics of ...

Analytical solution for the MTPV hyperbola including the stator resistance

2016 IEEE International Conference on Industrial Technology (ICIT), 2016
In this paper a method is presented which allows to analytically calculate the Maximum-Torque-Per-Voltage (MTPV) hyperbola including the stator resistance. The method relies on a transformation of the voltage ellipse (voltage constraint) to its principle axis system.
