Abstract:
The invention relates to an inverter circuit for the alternating connection of the phases of single-phase or multi-phase, in particular three-phase load (M) to the positive and to the negative terminal of a DC source (U B ), having pairs of electronic switches (T 1 , T 2 , T 3 , T 4 , T 5 , T 6 ) connected in parallel with one another and integrated into a power module ( 1 ), wherein the two switches belonging to the respective pair are connected in series, and wherein the connection for the respective phase (M 1 , M 2 , M 3 ) of the load (M) is provided at the connection of the two electronic switches belonging to the pair, having an intermediate circuit capacitor (C ZK ), which is connected in parallel to the DC source (U B ), and electric connections ( 2, 3 ) between the intermediate circuit N capacitor (C ZK ) and the power module ( 1 ) for the connection of the switch pairs (T 1 , T 2 , T 3 , T 4 , T 5 , T 6 ), wherein the electric connections ( 2, 3 ) have distributed parasitic inductances (L PAR ) and, as a result, cause electrical oscillations when switched, comprising a circuit arrangement for regenerative damping of the electrical oscillations, having a buffer capacitor (C buff , which is connected by the first connection thereof to a connection of the switch pairs (T 1 , T 2 ; T 3 , T 4 ; T 5 , T 6 ), a first diode (D high ), via which the buffer capacitor (C buff ) is connected to the other connection of the switch pairs (T 1 , T 2 ; T 3 , T 4 ; T 5 , T 6 ), further diodes (D low1 , D low2 , D low3 ), via which the buffer capacitor (C buff ) is connected to the connections for the respective phase (M 1 , M 2 , M 3 ) of the load (M), and a step-down controller (T S ), via which the buffer capacitor (C buff ) is connected to the intermediate circuit capacitor (C ZK ).

Claim (Index 11):
The inverter circuit as claimed in  claim 1 , in which the load (M) is a three-phase electric motor and its windings are interconnected in delta.
