In this paper, the problem of power waveform synthesis using the PASC technique to produce a desired output from a single dc source is introduced. Although the specific example discussed here is for a diagonally connected magnetohydrodynamic (MHD) generator, the technique can be applied to any single terminal pair source, with appropriate modification in power extraction interface and computer control program to match source and load impedance characteristics. The principal benefit of this system for the single output source diagonal MHD generator is that quantized sinusoids can be generated having low harmonic content and power factor control without the need for large and expensive filtering and VAR compensation such as is required for conventional inverters. After an introduction to the converter system topology for a single dc source along with the transformer representation employed, the simulation results for two and eight level PASC inverter systems are presented.
