    • The present invention relates to a method for the operation of an electrical circuit taking the form of a multi-level half-bridge (MLHB), and a multi-level half-bridge designed for implementation of the method, comprising two connections (A
      1 , A2), to which a bridge voltage (UBr) is applied and which are connected via two symmetrical branches (Z1, Z2) meeting at a central connection (M), wherein a central voltage (U
      M ) is applied to the central connection (M) against the potential of one of the connections (A
      1 , A
      2 ). Each branch comprises a number n of switch elements (Τ
      1 ,..., T
      n ; T
      n+1 ,..., T
      2n ) that are connected in series, can be switched to various switching states (Z) using a control unit, and are connected via suitably wired capacitors (C
      1 ,..., C
      n-1 ). A desired central or bridge voltage to be selected from specifically defined voltage levels is specified at a given bridge voltage (U
      Br ) or central voltage (U
      M ). As long as no other central or bridge voltage is specified, the circuit is then operated in a regulated operating mode in which initially all capacitors (C
      i ) are charged to a specific voltage and in which the voltage at the individual switch elements does not exceed a specified value. The specified central or bridge voltage is maintained by implementing individual switching states in a switching sequence grouped into switching cycles, in which sequence each switching state is active for the same duration and for the same number of times when the load on the multi-level half-bridge is constant so that in each switching cycle, each capacitor is charged and discharged for the same duration and the same number of times. In the event of a change between two adjacent voltage levels, a single switching element (Τ
      1 ,..., T
      n ; T
      n+1 ,..., T
      2n ) is switched for each branch (Z1, Z2).
