Patent number: 8379411Abstract: The present invention relates to voltage transformers, comprising multi-layer structures of piezoelectric ceramics, so-called piezoelectric transformers. The present invention further relates to switched mode power supplies, comprising such a piezoelectric transformer as part of a piezoelectric converter. The piezoelectric transformer according to the invention comprises a primary-side electrode arrangement (102) that can be connected to the primary-side voltage, a secondary-side electrode arrangement (104) on which the secondary-side voltage can be tapped, and an auxiliary electrode arrangement (106) for creating an auxiliary electrode voltage proportional to the secondary-side voltage, wherein the auxiliary electrode arrangement (106) is formed by at least two plane electrodes located opposite one another.Type: GrantFiled: June 9, 2008Date of Patent: February 19, 2013Assignee: Flextronics AP, LLCInventors: Michael Bothe, Stefan Mörbe

Patent number: 8072783Abstract: The invention relates to an input circuit for a logic circuit part, comprising a voltage converter component for conversion of a mains voltage to the required low voltage in order to supply a user with a low voltage. The supply to the input circuit may hence be connected to a mains supply to rectify the mains voltage and an output from the input circuit may be connected to the voltage converter component to provide a rectified input voltage for the voltage converter component. According to the invention, an improved input circuit for a logic circuit part with improved functionality and operating security also permitting an extensive miniaturization and simplified production may be achieved by replacement of at least two of the remaining four diodes in the rectifier part of an input circuit for a logic circuit part by two controllable switches which work as a synchronous rectifier and are connected such as to be switched on and off by alternate forced control.Type: GrantFiled: May 4, 2006Date of Patent: December 6, 2011Assignee: Power Systems Technologies GmbHInventors: Stefan Mörbe, Michael Bothe

Patent number: 7688597Abstract: The present invention relates to a power supply circuit comprising at least one transformer which is connected to a primary side circuit and to a secondary side circuit. The present invention further relates to a method for producing such a power supply circuit. To provide an improved power supply circuit which has a reduced size and increased power density and offers more flexibility in the formation of the safety distances between primary side and secondary side, the primary side circuit and the secondary side circuit are each mounted on at least one separate circuit carrier, said circuit carriers being mechanically and electrically coupled to one another and arranged in at least two different planes. According to advantageous embodiments, said circuit carriers may be arranged in planes that are either parallel with or transverse to one another.Type: GrantFiled: May 6, 2004Date of Patent: March 30, 2010Assignee: Power Systems Technologies GmbHInventors: Michael Bothe, Stefan Morbe, Michael Becks, Peter Grad
