<p>The inverter (1) has two bridge branches (Z1, Z2) with switching elements (S1-S6), and diodes (D7, D8) provided in opposite conducting directions. The diodes are attached between an alternating voltage terminal of the bridge branch (Z2) and a connecting point corresponding to the switching elements (S5, S6) and/or connecting points between the switching elements (S1, S2) and/or the switching elements (S3, S4). The diodes are attached, such that one of the switching elements (S2, S3) and one of the diodes carry freewheeling current in decoupled state of direct voltage of the inverter. An independent claim is also included for a control method for converting electric direct voltage into alternating voltage using an inverter.</p> |
