A method for regulating voltage in a pulsed power system having a resonant charging network coupled to a storage capacitor, a DC power supply network coupled to the resonant charging network via a first switch, an output load coupled to the storage capacitor via a second switch, and a de-Q-ing network coupled to the resonant charging network via a third switch, the first, second and third switches being triggered by a first trigger pulse, a second trigger pulse, and a third trigger pulse, respectively, the method comprising generating said third trigger pulse at a time that is a function of an initial voltage V.sub.1 (0) of the power supply network and a present voltage V.sub.2 (t) of the capacitor.
