  • Patent number: 11913424
    Abstract: An apparatus is described for converting river, tidal or ocean current energy into another form of energy, such as electrical, mechanical, or chemical energy. The apparatus can include a first underwater sail(s) coupled to a first cable and second underwater sail(s) coupled to a second cable. The sails are configured to catch water flows and move their respective cables along pulleys. The first cable and the second cable can form a main cable loop that is coupled to a bull wheel. A second cable loop configures the sails to best catch the water flow. The pulleys can guide the main cable loop along a rotational direction. The rotational movement of the bullwheel can be transferred to a generator to convert the water flow into another form of energy.

  • Patent number: 11855547
    Abstract: The invention relates to a method for feeding electrical power into an electrical supply grid. The method includes rectifying a first AC voltage of an electrical power, produced by a generator, into a first DC voltage and increasing the first DC voltage to a second DC voltage such that the second DC voltage has a step-up ratio in relation to the first DC voltage. Alternatively, the method includes rectifying the first AC voltage into the second DC voltage without producing the first DC voltage. The method includes inverting the second DC voltage into a second AC voltage for feeding electrical power into the electrical supply grid depending on an feed setpoint value and setting the second DC voltage depending on the feed setpoint value and actual value. The second DC voltage is increased depending on an increase in the feed setpoint voltage or actual value.
