Claim 0:
1. A pulsed direct current (DC) power delivery system, comprising:
a main pulser configured to deliver DC pulse waveforms to a main pulser output; and
a power module electrically coupled to the main pulser output of the main pulser, the power module configured to control an ion energy distribution function of ions within a formed plasma, the power module comprising:
a voltage source or a current source, wherein the voltage source or current source is electrically coupled between the main pulser output and ground, and wherein the voltage source or the current source comprises at least one of a DC voltage source electrically coupled in series to a resistor, a DC current source, or a shaped DC pulse voltage source; and
a switch electrically coupled in parallel with the voltage source or the current source, and between the main pulser output and the ground.
