    • The invention relates to an on-load transformer tap changing system wherein the secondary or primary of a transformer comprises at least one first and one second taps (p1, p2). A main connection circuit (tra-I2) is used for the permanent connection of the first tap (p1) or the second tap (p2) to an output terminal (b2) of the secondary or primary of the transformer. Secondary connection circuits (I1, I3) are each used to connect a tap (p1, p2) temporarily and directly to said output terminal (b2) of the secondary or primary of the transformer. Each of said connection circuits (I1, tra-I2, I3) comprises one or more insulated gate bipolar transistors and the system can be controlled without zero current value transition detection in the secondary winding. Application: Power transformers.

    • The control path of the switch (I) comprises an input stage (T2, T1) having an input (H) coupled to the input (E) for the control signal and having its output coupled to the control electrode (G) of the switch (I). A protection circuit (D1, Z2) coupled between the load (C) and the control path includes a threshold effect component (Z2) and a decoupling element (D1). On being made conductive by the current that results from a surge generated in a circuit of the load (C), the protection circuit (D1, Z2) is coupled to the input (H) of said input stage (T2, T1) to act on said switch (I) in the same way as a control signal for the switch (I). In this manner, the control path prevents current in the load (C) from dropping off suddenly.
