    Abstract: A multilever staircase generator employs a transformer having a core fabricated from a square loop magnetic material. The secondary winding of the transformer is shunted by a capacitor while the primary winding forms part of a controllable current loop, whose path is selected by activation of a suitable thyristor. During a first mode the secondary capacitor is charged to a stepped up, high-voltage level by causing a lower voltage to appear across the primary winding, after the activation of a first thyristor. A second mode occurs after the secondary capacitor transfers sufficient energy to saturate the secondary winding inductance and cause core switching; at which time the capacitor is charged to an opposite polarity. A third mode is provided by activating a second thyristor, which causes the secondary capacitor to transfer the energy stored thereby to a reactive impedance element located in the primary winding and switched into a suitable path by said thyristor activation.
