    摘要: The invention relates to an electrical circuit comprising a half-bridge (HB) having at least two transistors (T1, T2), a central connection (M) and a voltage supply, with which circuit an output voltage (U
    A ) which is switchable between at least two voltage levels can be set to a reference potential (U
    0 ) by suitable switching of the at least two transistors (T1, T2). The electrical circuit has an auxiliary circuit (HS), which is connected to the central connection (M) of the half-bridge (HB) and has, for its part, at least two inductances (L2, L3), at least two transistors (T3, T4), at least two diodes (D1-D4) and at least two capacitances (C1-C6). The auxiliary circuit (HS) is in this case configured for the purpose of reducing power losses in the half-bridge (HB) in such a way that a current flow is generated by coordinated switching of at least one transistor (T3, T4) in the auxiliary circuit (HS) with switching operations of the transistors (T1, T2), said current flow enabling virtually current-free switching-off of the transistors (T1, T2) in the half-bridge (HB) and/or virtually voltage-free switching-on of the transistors (T1, T2) in the half-bridge (HB). The circuit is designed to bring about quick demagnetization of one of the at least two inductances (L2, L3) during operation of said circuit by virtue of the energy stored in the inductance (L2, L3) being transmitted into the voltage supply by opening of one of the transistors (T3, T4) in the auxiliary circuit (HS).

    摘要: The invention relates to a device and method for measuring the periphery of a body. To this end, the device comprises at least the following elements: A wire which has a known longitudinal section with a length LD; a position sensor (4) which is in active contact with the wire (5) such that a signal S is emitted as soon as the wire (5) exerts at least one predetermined tractive force Z on said position sensor (4); a drive device (6, 7) for tensioning the longitudinal section of the length LD of the wire (5) along the periphery (2) of the body (3). The drive device (6, 7) is connected to the position sensor (4) in such a way that the wire (5) is no longer tensioned when the signal S is emitted. The inventive device also comprises a path-measuring sensor which is in active contact with the drive device (6, 7) and which is provided for measuring the path WD over which the wire (5) travels when tensioned along the periphery (2) of the body (3) by said drive device (6, 7) so that the periphery (2) of the body (3) can be determined (150) from the length LD, from the path WD and from a device-dependent geometry factor G.
