  • Patent number: 9800160
    Abstract: The invention relates to a switched-mode power supply (14) for supplying the components of a photovoltaic system (1) with a constant DC output voltage (Ua), comprising connections (15) for connecting to the photovoltaic modules (2) of the photovoltaic system (1) for providing a DC input voltage (Ue), a DC/DC voltage converter (16) comprising at least one switch (17), a transformer (18), a control device (22) for controlling the at least one switch (17) at a switching frequency (fs) for obtaining the desired DC output voltage (Ua), an output equalizing voltage (23) and connections (24) for providing the DC output voltage, as well as the inverter (4) and a string monitoring assembly (3) of a photovoltaic system (1). In order to obtain a DC output voltage (Ua) with the losses as low as possible for a very wide range of DC input voltages (Ue) between 200 V and 1500 V, the DC/DC voltage converter (16) is formed by a combination of flyback and forward converters having two serially arranged switches (17, 17?).

  • Patent number: 9151487
    Abstract: The invention relates to a heating element (25) for liquids to be vaporized as well as a burner (6) of a steam cutting device (1) and a burner (38) of a power-generating device, the element being designed as an induction heater (47) comprising one coil (25a). In order to improve vaporization, the coil (25a) of the induction heater (47) is enclosed in a hybrid construction which is composed of a main part (31) with laterally extending webs (33), and which consists of an easily magnetizable material (35) and a thermally highly-conductive material, a covering element (32) consisting of nanocrystalline materials being arranged on the webs (33), and the easily magnetizable material (35) being designed to be installed on a thermally highly-conductive material (37) of a vaporizer (21).
