Analysis of Output Characteristics of Photovoltaic System
Advanced Materials Research, 2012The output of photovoltaic generation system is influenced by the factors such as solar radiation, temperature and so on. So the change of photovoltaic generation power is a non-stationary random process that will impact on the grid. In order to promote large-scale photovoltaic generation connected to the grid, we need to configure energy storage ...

Output Current-Voltage Characteristic of a Solar Concentrator
2010Solar concentrators have received much attention in their potential applications. In solar concentrators the generated current is directly affected by hourly- daily variation factor and the number of suns. In this paper the output current-voltage characteristic of a solar concentrator is derived.

Pressure dependence of copper laser output characteristics
Applied Optics, 1993Output characteristics of a large-bore (8-cm-diameter) copper laser were analyzed at different neon pressures. Radial delay decreased from ∼40 ns at 30 Torr to ∼10 ns at 110 Torr because of increased plasma impedance. When the laser was running as an amplifier, the best power was achieved at approximately 80 Torr (small-bore copper lasers normally ...

Output power characteristic of WEC for a buoy
Journal of Mechanical Science and Technology, 2009Floating devices, such as a cavity resonance device, take advantage of both the water motion and the wave induced motions of the floating body itself. In the design of a wave energy converter (WEC), the most significant factor is that an optimum length of the internal water column should exists, that is, a length in which maximum power is converted ...

Power Output Characteristics of a Ruby Laser
Journal of Applied Physics, 1961The theoretical power output of a ruby laser is examined under certain idealized operating conditions, and it is found that there are two principal regions of operation. These are the regions of strong oscillation characterized by the condition pτ2/A»hν13/σ13 and the region of saturation in which pτ3/A»hν13/σ13. Here p/A is the ``pumping'' illumination
