Patent Images
1. A pulse generator, comprising:
- a pulse waveform generator that generates a pulse waveform having at least one first phase of the pulse waveform and at least one second phase of the pulse waveform, wherein the first phase has an amplitude whose value is less than an amplitude of the second phase and wherein the first phase has a polarity and the second phase has an opposite polarity to the first phase;
at least a first subsystem that generates at least the first phase of the pulse waveform, the subsystem having a power source and an energy reservoir;
at least a second subsystem that generates at least the second phase of the pulse waveform, the second subsystem having a second power source and a second energy reservoir; and
a control logic unit that controls the first and second subsystems to generate the pulse waveform having the at least one first phase and the at least one second phase.
