Abstract
A matrix inverter is connected to a first and a second multi-phase A.C. voltage network. First inductive elements are connected to the first A.C. voltage network and second inductive elements are connected to the second A.C. voltage network. A switch matrix connects the ends of the first inductive elements, to the ends of the second inductive elements. The switch matrix has inverter units. A regulation arrangement is connected to control inputs of the inverter units. The matrix inverter has a first inverter unit, which is arranged between the ends of the first inductive circuit elements and earth potential. The matrix inverter has a second inverter unit, connected between the ends of the first inductive circuit elements and the ends of the second inductive circuit elements. The regulation arrangement insures that the electrical power flowing to the matrix inverter is equal to the electrical power flowing out of the matrix inverter.
