PROBLEM TO BE SOLVED: To specify a direct converter that exchanges electrical energy between two-pole switching cells of direct converter. SOLUTION: The direct converter 1 including n input phase connections U1, V1, W1 and p output phase connections U2, V2, W2 is specified, wherein n≥2 and p≥2. The direct converter also includes (n×p) two-pole switching cells 2 for switching at least one positive voltage and at least one negative voltage between the poles. Each of the output phase connections U2, V2, W2 is connected in series with the respective input phase connections U1, V1, W1 via a switching cell. To enable any desired and continuous current flow setting from an input phase connection to an output phase connection of the direct converter and, moreover, to exchange an electrical energy between the two-pole switching cells of the direct converter, at least one inductance 3 is connected into each series connection. A system including series connection is also provided. COPYRIGHT: (C)2011,JPO&INPIT |
