The supply circuit from power generates has capacitor bank charged slowly by the generator output current and then rapidly discharged across the load. Each capacitor circuit consists of a capacitor coupled via a rectifier diode to the generator, and via a power transistor switch, such as a triac and rectifier bridge to the load. The capacitor circuits are connected in parallel between the generator output and the load, and any number of them may be switched in bu turning on various power transistor switches across the load. The capacitor circuits may be divided into two groups, each group being connected over a high voltage transistor to the generator second output terminal.
