In an invertor circuit in which two power field-effect transistor switches, which are connected in series and conduct in reverse, are connected to a DC voltage source and the load is connected between the junction point of the two transistors and the two poles of the DC voltage source, the slow transition of the integrated inverse diodes, which are present in the field-effect transistors, from the conducting mode to the blocking mode is a disturbing factor. For this reason, fast, discrete diodes (D1, D2) with very good low characteristic forward values, i.e. threshold voltage and equivalent resistance, are connected in parallel with the source-drain junctions of the field-effect transistors (T1, T2), the conducting-state voltage of the fast additional diodes (D1, D2) not reaching the threshold voltage of the integrated (parasitic) inverse diodes (DT1, DT2) of the field-effect transistors (T1, T2). The integrated inverse diodes (DT1, DT2) do not then participate in the current supply. <IMAGE>
