In this paper, a new concept of bi-directional battery charger for PHEV/EV with photovoltaic generation system and operation algorithm of battery charger system is proposed. A novel battery charger system with photovoltaic generation is designed to have function of photovoltaic power conversion and battery charging/discharging. Also, considering sensitive photovoltaic source according to in the environment...
In this paper, according to power sharing algorithm and types (2 Con & 2 Inv, 2 Con & 1 Inv, 1 Con & 1 Inv) of photovoltaic (PV) and fuel cell (FC) hybrid generation system, control algorithms of converter and inverter are presented. Almost algorithms of PV and FC hybrid generation system are performed and verified to use by technology for commercialization. Moreover, a comparative study...
An embedded systems like e-Book where it consumes less power and employs greatly in outdoor environment, solar energy can be introduced for extending the reading time. In this paper, to design e-book system with photovoltaic solar cell application, solar harvesting module must be considered. But measurement showed that charging current for battery is significantly affected by solar cell type and the...
In this paper, based on Matlab which has characteristic that is simply applied to control algorithm and source modeling, photovoltaic modeling is implemented. Photovoltaic modeling is similarly performed PV array and simulated. Also, in order to output maximum power of PV, MPPT control is simulated. Moreover, simulation of converter is performed by means of PLECS (piece wise linear electrical simulation)...
Conventional popular MPPT methods are effective under uniform solar irradiance. However, under partially shaded conditions, these MPPTs can fail to track the real MPP because of the multiple local maxima which can be existed on PV characteristic curve under partially shaded condition. In spite of some researchers have worked on real MPP tracking under partial shading conditions, the methods have some...
This paper presents a transformerless grid-connected photovoltaic (PV) system with active and reactive power control. The proposed system operations can be categorized into sunny mode and night mode. In night mode, it compensates for the reactive power demanded by nonlinear loads. In sunny mode, it not only supplies active power from the PV array to the grid or loads, but also performs power quality...
