<p>Cascaded transistor stages are connected between a high voltage and a discharge resistance coupled to a lower potential. The transistor stage closest to the lower potential is referred to as a driver stage, and all the other transistor stages are referred to as component stages. Blocking diodes are connected across all stages, forming a continuous path from the high voltage to ground. When an enable signal is provided to the driver stage, the transistor stages sequentially enter a conduction, starting with the driver stage and proceeding to the component stage coupled to the high voltage. The current flow through the driver stage is regulated and remains relatively constant as the high voltage is brought to close to the lower potential. The voltage drop is approximately linear, ensuring that voltage ringing or rebound does not occur following the discharge. After the high voltage is brought to the lower potential, the transistor stages remain in conduction as determined by the presence of the enable signal, to discharge any remaining high voltage that may be attached through a high series impedance. Upon removal of the enable signal, the transistor stages no longer conduct.</p> |
