  • Patent number: 8934275
    Abstract: The invention relates to converters for converting a DC input voltage a DC or an AC output voltage. The converters have a parasitic inductance. The converters comprise at least one switching element connected to an input terminal for providing a first voltage at an output terminal. In order to allow temporarily storing, in a capacitor, energy induced by the parasitic inductance when switching OFF the switching element, a first series circuit of a diode and a capacitor is provided in the converter, wherein the diode is coupled to the one input terminal. An active circuit coupled in parallel with the diode enables controlling the release of temporarily stored energy from the capacitor of the first series circuit.

  • Publication number: 20130128644
    Abstract: The invention relates to inverters employing a first and a second bridge circuit for converting DC input current into an AC output current. In particular, the invention proposes an inverter including two DC input terminals with a first and a second bridge circuit connected in parallel therebetween, the first bridge circuit for providing a first half-wave of a first polarity to a pair of AC output terminals and the second bridge circuit for providing a second half-wave of an opposite polarity to the pair of AC output terminals. The first half-wave is supplied from the first bridge circuit via a first and a second inductive element to the pair of AC output terminals, and the second half-wave is supplied from the second bridge circuit via a third and a fourth inductive element to the pair of AC output terminals.

  • Publication number: 20120019230
    Abstract: A DC/DC converter circuit to be used in the field of MPPT for solar inverters, for step-up DC/DC conversion for high output voltages, and for chargers in electrical vehicles. The circuit comprises a first DC terminal and a second DC terminal, a first DC voltage being defined there between. It further comprises a positive split DC terminal and a midpoint terminal, a positive split DC voltage being defined there between. A negative split DC terminal is provided, a negative split DC voltage being defined between said negative split DC terminal and said midpoint terminal. A first switch and a second switch are provided, and a converter inductance is storing electric energy therein. A first diode is connected between a first terminal of said first switch and said positive split DC terminal, and a second diode is coupled between an internal midpoint and said midpoint terminal.
