A static converter, including at least one pair of mutually co-acting switching transistors (TR1, TR2), of which the first switching transistor (TR1) is controlled with a frequency exceeding the control frequency of the second switching transistor (TR2). A diode (D1, D2) is connected between the emitter and collector of respective switching transistors. The noval feature of the invention resides in that a voltage source (N1, P) is activated when the first switching transistor (TR1) is energized to its conducting mode (IR) and to supply a reverse recovery current (Irr) through the diode (D2) of the second switching transistor in the reverse direction of the diode.
