Distributed photovoltaic power optimizers and control method

The invention relates to distributed photovoltaic power optimizers and a control method. When series connection and parallel connection of photovoltaic modules are mismatched due to factors such as partial or intermittent shielding or aging of photovoltaic arrays, the control method is more obvious in effect. The control method is characterized in that after directly attached to photovoltaic modules, the power optimizers are connected through a series connection framework, and the power optimizers in the series connection framework firstly obtain voltage signals and current signals of the photovoltaic modules connected with the power optimizers and directly perform maximum power tracking on the single module, so that the photovoltaic modules output maximum power, and results are transmitted to a central controller. The central controller receives the maximum power calculated by each optimizer, voltage and current conditions of the shielded modules are monitored, and the voltage and current output by all the modules are coordinated through calculation. The control method not only can ensure that each photovoltaic module works at an optimal working point, but also can enable setting of bus voltage to be more flexible and stable, and the system can serve as a direct-current power supply and also be used for an independent or grid-connection photovoltaic system.

Sealed cover for recessed lighting fixture

The present invention relates to a cover for a recessed light fixture, having a housing composed of heat-tolerant material, and having visible trim ring (12), and a means for retaining said cover to said fixture (10). Light generated by the recessed light fixture will pass through the lens (14), which may be transparent, translucent, or colored. The present invention is sized to fit within the baffle of a preexisting recessed light fixture (15), to which the present invention may be frictionally engaged, and over the outer trim of such a fixture (17), to which the present invention will form an airtight seal through the use of a seal ring (16). The present invention seeks to promote energy efficiency by providing an airtight barrier which inhibits the passage of conditioned (furnace-heated or air conditioner-cooled) air through the recessed light fixture and out of the living space. Energy efficiency is also promoted by encouraging (though not necessitating) conversion from incandescent bulbs to compact fluorescent bulbs. Further, the airtight barrier has the desirable effect of prohibiting the movement of insects through the recessed light fixture and into the living space. The present invention can be easily installed without tools or special skill, and can be easily removed to allow for bulb replacement. It can be manufactured in varying shapes and sizes, including sizes conforming to standard recessed light fixtures having circular openings with 4-inch and 6-inch diameters, and with tapered and non-tapered baffles.
