After a brief introduction about the polarization curve, this paper addresses a new method for correcting the values of measured voltages. By knowing this, it is possible to determinate, by a mathematical regression, the parameters allowing to describe the electrical behavior of a PEM fuel cell system. These parameters, obtained by experimental setup permit a fuel cell stack model to be obtained in...
Quality assurance testing of mass-produced electrical appliances is critical for the reputation of the manufacturer since defective units will have a negative impact on safety, reliability, efficiency, and performance of the end product. It has been observed at a brushless DC compressor motor manufacturing facility that improper magnetization of the rotor permanent magnet is one of the leading causes...
An improved AC standstill inductance measurement method for interior permanent magnet synchronous machine (IPMSM) is proposed in this paper. Only the 3-phase voltage source, oscilloscope, and DC voltage source are required in this method, rather than the dynamometer and vector controller in the other methods. Depending on the derivative q- and d-axis voltage equations in the stationary reference frame,...
In this paper, a new flicker contribution tracing method has been proposed to determine the individual flicker contributions of multiple electric arc furnace (EAF) loads to the flicker measured at the point of common coupling (PCC). The proposed method decouples the flicker contribution of the interconnected electricity system from the individual contributions of the loads connected to the measured...
