摘要

An inverter with high-speed switching, controllable electronic switches, in particular igbt - switches, in a full bridge circuit, which provides a first bridge-arm pair with two switches and a second bridge-arm pair with two switches, each bridge-arm pair at its two ends in each case to the positive and negative pole of the input voltage source is connected and the center points of the bridge-arm pairs via the primary winding of an output transformer for the formation of a first and a second bridge diagonal are connected to one another, characterized in that in each case one of two switches (t3, t4) of the full bridge circuit, which do not lie on a common bridge diagonal, together with a direct current - storage inductor (l) and a diode (d1, d2) are connected as a step-down converter, whereby this switch in each case with a pole of the input voltage source (u_a+/U_a–) in the reverse direction and via the diode (d1, d2) with the other pole of the input voltage source are connected and the direct current - storage inductor (l) two windings (l1, l2), the inductively strongly and are coupled capacitively weakly, wherein at least one of the windings (l1, l2) with..
