Abstract:

Effort was directed towards circuit design to improve the switching characteristics of the current feedback oscillator so that efficient operation can be achieved at higher frequencies. A low input voltage converterregulator model was fabricated by using new bias circuitry. This model was specifically designed for operation from a source consisting of two series connected fuel cells. Arrangements were made to test this converter from a two cell fuel cell. A converter-regulator model was designed for operation from a single thermionic diode with a terminal voltage in the 0.4 volt to 0.8 volt range. This model will be designed to accommodate a 150 ampere input current and will have a regulated 28 volt output. This model will be packaged in a cylindrical shape and the outer surfact will form the negative bus bar. Piece part drawings were completed and fabrication of this unit will commence shortly. Tentative arrangements were made to test this converter with a single thermionic diode.
