Abstract: A radiofrequency generator employing a charging inductor connected to a source of direct current (DC) energy through a charging switch. The capacitor of a radiofrequency (RF) tank circuit cooperates with the charging inductor to achieve resonant charging of the RF tank circuit. A power switch is closed causing the charged tank circuit to oscillate at its natural resonant frequency through a series-connected load.
