Electronic control circuit for use in combination with an electric charge supply device having a load connection (OA), a high voltage supply connection and a common line, and with an electronic switch (13) switches the high voltage supply connection to the load connection. This electronic switch (13) has an inlet (15) and is responsive to a voltage difference between the input and the load connection. The load connection (OA) under severe voltage excursions relative to the common line due to the cutting. The electronic control circuit comprises a transformer (51) having a primary winding (53) and a secondary winding (55) producing at least one output pulse signal, the transformer having an inherent capacitance interleaving (Cw) between the winding primary and the secondary winding. A circuit connected to the secondary winding couples the output pulse signal of the secondary winding between the input (15) of the electronic device and the load connection (OA) when the pulse output signal is present. A high voltage excursion on the load connection charging the product of the inherent capacitance interleaving (Cw) to a high voltage level when the pulse output signal is present. The electronic control circuit further comprises branch circuits of the high voltage level on the inherent capacitance of the transformer interleaving to the load connection when the pulse signal output and each voltage excursion cease, and a circuit active control (75) having an input and first and second control lines and a resistive path (81, 89) having substantially no inductance between the input (83) of the active control circuit and the inlet ( 15) of the electronic switch. The active control circuit then performs the switching of the current
