A power supply system of an embodiment has a plurality of power conditioners, an acquisition device, and a search instruction generator. The power conditioners convert a form of electrical power generated by a plurality of electrical generators into a different form of electrical power. The acquisition device acquires a respective information regarding power output from each of the plurality of power conditioners. The search instruction generator generates and outputs an operating point search instruction to one or more power conditioners being lower in a ratio of output power with respect to a reference power by at least a prescribed degree than one or more different power conditioners, wherein the reference power is given, based on the maximum output power or rated power of the corresponding electrical generator, or based on the maximum output power or rated power of the power conditioner.

Power supply system

A control device includes a searching unit increasing or decreasing, at a predetermined step width, an operation voltage or an operation current of a power supply connected to a power converter to search a maximum power point of the power supply, a consecution time determining unit determining whether or not the searching unit has consecutively increased or decreased the operation voltage of the power supply or the operation current thereof, and a step width increasing unit increasing the step width upon determination by the consecution time determining unit that the increase or the decrease has been consecutively executed by a predetermined number of times.

Control device for power converter, control program and power conversion device

According to one embodiment, an inverter includes a housing having a corner, a DC terminal, an electronic component, an AC terminal, a wireless communication module, and a projection mechanism. The DC terminal inputs DC power. The electronic component converts the DC power input to the DC terminal into AC power. The AC terminal outputs the AC power from the electronic component to the outside of the housing. The wireless communication module includes an antenna which receives or transmits a signal for controlling the electronic component. The projection mechanism projects at least a part of the antenna into the outside of the housing. The projection mechanism is provided in a portion of the housing other than the corner.

Inverter and photovoltaic apparatus

A broadcast receiver includes: an image analyzer configured to perform an analysis on a series of images; a recorder configured to record a result of the analysis and the series of images; and an image processor configured to perform image processing on a target image included in the series of images recorded in the recorder based on the result of the analysis performed for images subsequent to the target image.
