Abstract
In an inverter includes two input lines for connection to a DC voltage source, two half-bridges connecting the two input lines, and two output lines for connection to an alternating current load or an AC power grid. Each half-bridge includes two pulse-operated switches with reverse connected diodes, each output line is connected to a center point of one of the half-bridges via an inductance, and the two output lines are connected to the same one of the input lines via a further pulse-operated switch behind the inductance with respect to the associated half-bridge.
