The advent of new power sources such as the fuel cell, thermionic diode, and thermoelectric generator has provided the stimulus for the investigation of low input voltage conversion. Since the voltage output of a single energy conversion cell is too low for most applications, it must be stepped up by either adding cells in series or by a converter. Series connection of some direct conversion sources is difficult, increases cost, reduces reliability, and may require monitoring and parameter control of each cell. The use of a single, large capacity power source cell or a minimum number of series connected source cells coupled to a converter, is considered a tentative and attractive solution to this problem. The initial effort under this contract was specifically directed toward the investigation of all known approaches to determine the optimum and presently most feasible approach to convert the low source voltage of fuel cells, thermionic diodes, thermoelectric generators, solar cells, and single-cell batteries to more usable higher voltages.
