Painting a V-shaped surface, which is widely found in various facilities and equipment, often results poor coating quality, may be caused by an insufficient understanding of film-forming characteristics mechanism. In this study, computational fluid dynamic (CFD) simulations were carried out for in-depth research on the mechanism painting surfaces. The mathematical model film formation was estab...

Photovoltaic array exhibits highly nonlinear electrical characteristics and the maximum power point tracking (MPPT) is always challenging. It becomes more complex during partial shading condition. The P-V array characteristics for shading condition have multiple maxima points and conventional MPPT technique fails to track global maximum power point. The operating point may settle at local point...

This paper presents an improved electronic circuit for testing photovoltaic (PV) modules or strings by tracing their I-V and P-V characteristics. It consists of an electronic fast varying load based on a power MOSFET controlled by means of an innovative sweeping gate-source voltage in order to improve the tracing of the I-V characteristics on an oscilloscope. In order to prevent damage of data ...
