The invention discloses a method, together with circuits for performing these actions, of driving a capacitance with a quasi-square wave of variable duty cycle and frequency in such a manner that the energy stored in the capacitor is not lost. The energy is actually recycled to be stored back in the capacitor again but with an effective opposite polarity voltage. The circuits to achieve this operation comprise of the capacitor to be driven, coupled to an inductor which is driven by either two switches and two diodes, or by two bilateral switches and timing cirvuitry.
