Abstract
An electrical power pulse generator system and a method of the system's operation are described herein. A main energy storage capacitor supplies a negative DC power and a kick energy storage capacitor supplies a positive DC power. A main pulse power transistor is interposed between the main energy storage capacitor and an output pulse rail and includes a main power transmission control input for controlling power transmission from the main energy storage capacitor to the output pulse rail. A positive kick pulse power transistor is interposed between the kick energy storage capacitor and the output pulse rail and includes a kick power transmission control input for controlling power transmission from the kick energy storage capacitor to the output pulse rail. A positive kick pulse power transistor control line is connected to the kick power transmission control input of the positive kick pulse transistor.
