摘要:
The present invention relates to a voltage converter, a voltage converting method, a power adjuster, a power adjusting method, a photovoltaic system, and a management device which are capable of generating power with a higher output.In a photovoltaic system 11, each of the output converters 21-1 to 21-8, which converts a voltage of power generated by each of solar battery modules 22-1 to 22-8 to a voltage to be outputted to the outside, is provided with respect to each of the solar battery modules 22-1 to 22-8. In each of the output converters 21-1 to 21-8, an operation of a DC/DC converting part that executes a process for converting the voltage is switched to either conversion-rate fixing or maximum power point tracking control based on an amount of output power of the DC/DC converting part. The present invention is, for example, applicable to a photovoltaic system provided with an output converter with respect to each of solar battery modules.

摘要:
The present invention relates to a detecting device and method, and a program which can detect a power state easily at low cost. A current transformer measures current of a commercial power system from a commercial power supply through a connection point of the commercial power system and a power generation system from a solar power generation system that supplies power having the same frequency as the commercial power supply. A current transformer measures power at the power generation system side through the connection point. A decision value calculator calculates a decision value based on a value obtained through multiplication of a measured value of current through the current transformer and through the current transformer. A flow detector detects a power flow of the commercial power system based on the calculated value. The present invention can be applied to a power measuring system for use in homes, for example.

A detection device for detecting a state of electric power has a first current transformer that measures a first current on a first power line side of a connecting point between a first power line derived from a commercial power supply and a second power line derived from a power generation device which supplies electric power equal in frequency to the commercial power supply, a second current transformer that measures a second current on a second power line side of the connecting point, a first calculation unit that calculates a decision value based on a product of a measured value of the first current and a measured value of the second current, and a detection unit that detects a power flow direction of electric power of the first power line based on the decision value.
摘要:
Optical fiber guides are provided outside a waveguide mounting region of a supporting substrate. Optical fibers are provided so as to be fitted in the optical fibers, respectively. In addition, end faces of the optical fibers and end faces to which a core of an optical waveguide is exposed are opposed and almost parallel to each other. Furthermore, the end face to which the core of the optical waveguide is exposed is provided so as to form an acute angle with a surface of the supporting substrate. Thus, tip ends of the optical fibers are not likely to be shifted from the core in a thickness direction of an optical waveguide device.

Sensors are provided with information transmission units for transmitting power information to a mobile information terminal and a server. The server is provided with a server storage unit that stores power information for the duration of a second period. The mobile information terminal is provided with: a terminal storage unit that stores power information for the duration of a first period that is shorter than the second period; a power information acquisition unit that acquires power information from the terminal storage unit or the server, in accordance with a display period specified by a user; and a display control unit that displays the acquired power information.

A telephone apparatus of the present invention comprises a telephone number comparator for comparing a telephone number included in caller information delivered from caller identification delivery service with a telephone number registered in an electronic telephone directory, and displays the telephone number registered in the electronic telephone directory in display unit when the telephone numbers match at least in part as a result of the comparison. The telephone apparatus is thus able to display a correct telephone number of the incoming call and dial the telephone number correctly when making a callback.

摘要:
A hot-air supplying method that includes: generating, by means of a heat pump, hot air that is at a temperature lower than a desired target hot-air temperature; subsequently heating, by a heater, the hot air having been generated by the heat pump, while controlling the heater the temperature adjuster so as to adjust the temperature of hot air thus heated to the target hot-air temperature. This makes it possible to supply, with reduced energy loss and at low costs, hot air for processing a work, the hot air being necessary in a factory where processing and assembly or the like are carried out. Further, temperature control accuracy is enhanced.
