High energy pulse on a high-voltage-direct-current offset
Last updated:
Abstract:
Pulse power supply systems and methods are disclosed. A method includes providing earth-ground-referenced control circuitry and providing floating pulsed-power circuitry. The method also includes providing a DC offset voltage to the return port of the pulsed-power circuitry with a DC offset module and providing a peak voltage to the pulsed-power circuitry with a DC voltage source. Power is applied from a power source of the control circuitry to a driver of the pulsed-power circuitry via a galvanically-isolating power path and a trigger signal is applied from the control circuitry to the driver via a galvanically-isolated signal path to prompt the driver to produce a driver signal. A voltage pulse is produced between the output port and the return port by closing the switch with the driver signal to couple the peak voltage to the output port.
