摘要： In a power control system including a first controller configured to control supply of power from a photovoltaic module to a plurality of loads and a second controller configured to control charge/discharge of a storage battery, which is one of the plurality of loads, the first controller controls output following power consumption by the plurality of loads, and the second controller increases, during a self-sustaining operation, charging power of the storage battery and detects output fluctuation from the photovoltaic module or from the first controller along with the increase in the charging power, then based on the detected output fluctuation, controls charge of the storage battery, thus, even if connection to the grid is disconnected, supply power may be replenished by the load power used for supply to the predetermined loads, thereby allowing a stable power supply to the other loads.

摘要： A dc energy store (2) that includes auxiliary systems (68) can be operated in one or more different modes, including a self-supporting mode, an island mode and a normal mode. In the self-supporting mode a first controller (24) uses a voltage demand signal (VACr) indicative of desired ac voltage at the ac terminals of an AC/DC power converter (4) to control semiconductor power switching devices of the AC/DC power converter (4) to achieve the desired level of ac voltage that corresponds to the voltage demand signal (VACr). The voltage demand signal (VACr) is derived from a comparison of a voltage feedback signal (VACfb) and a second voltage demand signal (VACsr) that is preset to provide the desired ac voltage for the auxiliary systems (68) of the dc energy store. A second controller (46) uses a current demand signal (Ior) indicative of the desired dc link current to control the semiconductor power switching devices of a DC/DC power converter (14) to achieve the desired level of dc link current that corresponds to the current demand signal (Ior). The current demand signal (Ior) is derived from a comparison of a dc link voltage demand signal (VDCr) indicative of a desired dc link voltage and a dc link voltage feedback signal (VDCbus).

摘要： Different types of energy storage systems are described, in particular hydro-pneumatic storage systems. In one, energy is stored by compressing gas in a chamber (44,45,54,55) with a liquid piston and released by gas expansion. A spray head or grid at the top of the chamber (44,45,54,55) supplies liquid as a shower through the gas being compressed or expanding in the cylinder (11,12) to maintain an isothermal condition. In another, energy is stored from an array of solar cells connected to an array of supercapacitors forming an auxiliary storage, and a main energy storage device such as a hydro-pneumatic storage system, for supply to an AC or DC network. The efficiency is improved by connecting the solar cells via the array of supercapacitors to the AC or DC network. An immersed hydro-pneumatic storage device for off-shore/on-shore power generation systems comprises a cylinder that is immersed in a liquid mass, wherein energy is stored by compressing gas with a liquid piston and energy is released by gas expansion. The mass of liquid maintains an isothermal condition in the cylinder during compression and expansion.

摘要： This invention relates to an improved laser printer power supply that maintains 24-, 12-, and 5-volt DC power to run exhaust fans (14) for a brief period after the power switch (S1) is turned off. These fans (14) remove undesirable ozone from the photo-conducting print drum so as to extend the life of the photo-conductor. The circuits utilize a timer circuit and an optically isolated photo-diac (31,32) to turn a power triac (30) on and off.

摘要： The present invention relates to a power converter architecture and its operation principle that supplies an electric load with a controlled direct voltage from both a local direct current electricity source as well as an alternating current (AC) mains with maximum power conversion efficiency. For the case that the local electricity source can not provide enough electricity to the local load it is additionally supplied with electricity from the AC mains. In other case electricity is also feed into the AC grid when a local source can provide more electricity than needed to supply local loads.
