This paper discusses methods of generating high voltage waveforms (up to several thousand volts) at modest power levels (several ten's of watts). The circuit techniques and system configurations which involve Parallel Series Chains (PSC) of Light Triggered Bilateral Switches (LTBS) are new and employ all solid state components. The circuit and system techniques discussed show how small, light weight, highly efficient, programmable power systems can be built to satisfy a wide variety of applications and should be particularly interesting to those designing high performance and/or portable power systems.
