摘要

Matrix converter (MU), connected, on the one hand, with a first multiphase alternating current network (N1) and, on the other hand, with a second multiphase alternating current network (N2), - with in each case first inductive elements of circuit (Su1, Sv1, Sw1) connected to the first alternating current network (N1), and in each case second inductive circuit elements (Su2, Sv2, Sw2) 5 connected to the second alternating current network (N2), - with a switching matrix (MA), which connects the ends (Eu1, Ev1, Ew1) of the first inductive circuit elements (Su1, Sv1, Sw1) away from the first alternating current network (N1) with the ends (Eu2 , Ev2, Ew2) of the second inductive circuit elements (Su2, Sv2, Sw2) away from the second alternating current network (N2), whereby - the switching matrix (MA) consists of controllable converter units (Uu1, Uv1, Uw1; Uu2, Uv2, Uw2), - with a regulation arrangement (R) connected to the control inputs ation of controllable converter units (Uu1, Uv1, Uw1; Uu2, Uv2, Uw2), - where the regulation arrangement (R) is exposed to the measured current and voltage values of the first and second alternating current network (N1, N2), and - where it is connected between the ends of the first inductive circuit elements (Su1, Sv1, Sw1) away from the first alternating current network (N1) (Eu1, Ev1, Ew1) and the ends of the second inductive circuit elements (Su2, Sv2, Sw2) away from the second alternating current network (N2) (Eu2, Ev2, Ew2) in each case a second converter unit (Uu2, Uv2, Uw2) in an execution as a controllable source of alternating current, characterized in that - between the ends of the first inductive circuit elements (Su1, Sv1, Sw1) away from the first alternating current network (N1) and ground potential (M), in each case a first converter unit (Uu1, Uv1, Uw1) is arranged in a execution as a controllable source of alternating current, and - the regulation arrangement (R) is co net with regulating inputs of the first and second converter units (Uu1, Uv1, Uw1; Uu2, Uv2, Uw2) such that the electrical power that reaches the matrix converter (MU) is equal to the electrical power that leaves the matrix converter (MU).
