1. A pulsed-voltage generator circuit for producing a flash pulsed voltage for testing the capacitance of a unit under test, comprising:

  • at least one stage (1,2) which can be charged, said at least one stage (1, 2) having a surge capacitance (11, 21) and a switching device connected in series, a parallel resistor (13, 23) connected in parallel with the surge capacitance (11, 21) and the switching device, a series resistor (14, 24) connected in series with the surge capacitance, the switching device and the parallel resistor (13, 23), and a load capacitance (4), including the capacitance of the unit under test, connectable to said at least one stage (1, 2), said circuit having at least one additional circuit element (5, 5

    , 6, 7) which includes a compensation capacitance (51, 51

    , 61, 71) and at least one discharge element (52, 52

    , 62, 72) connected in parallel with the compensation capacitance (51, 51

    , 61, 71) to compensate for unwanted oscillatory overshoot of pulse fronts of the flashed pulsed voltage across the load capacitance (4).
