Abstract (en)

[origin: WO2009101352A1] High-voltage generator device, comprising an inductive-capacitive resonator (RS2) capable of producing a high voltage, means for generating a high-frequency control pulse train, a voltage source (VMT), a capacitor (C1) and a voltage generator (GENI) comprising a switching transistor (M1), the control electrode (G) of which is connected to the output of the means for generating the high-frequency control pulse train, the source (S) of the switching transistor (M1) being connected to ground, and the drain (D) of the switching transistor (M1) being capable of delivering a voltage pulse train to the inductive-capacitive resonator (RS2) in response to the control pulse train received on the control electrode (G) of the switching transistor (M1). The drain (D) of the switching transistor (M1) is connected to the inductive-capacitive resonator (RS2) via an isolating transformer (TRANS), the isolating transformer (TRANS) being connected in parallel with a capacitor (C1), the isolating transformer (TRANS) also being connected to the voltage source (VMT).
