LOW INPUT VOLTAGE CONVERSION.
Abstract
During this quarter, effort has been directed towards the design and fabrication of a low input voltage converter-regulator for test with a thermionic diode source. Also fuel cell-low input voltage converter-regulator load system tests have been conducted with excellent results. The 200 watt low input voltage converter-regulator fabricated during the previous quarter was operated from two series connected fuel cells and from a four fuel cell series-parallel stack. With the fuel cells as a source, the converter provided a 135 watt regulated 28 volt output with an efficiency of 85%. This system satisfactorily powered a 28 volt dc motor during starting, stalling, motor reversal, and normal running tests. The system also performed satisfactorily when subjected to slowly increasing overloads and sudden dead shorts. These tests have verified that the low input voltage converter-regulator circuit works well with a fuel cell source and that no unstable operating modes occur. Thus, fuel cell-low input voltage converter-regulator systems can provide a practical and reliable means of achieving useful higher voltage regulated power for operation of electronic equipment in remote areas. The fabrication of the coaxial model for use with a thermionic diode source has been completed and is currently being checked out in the laboratory. It is anticipated that tests with a thermionic diode source will be arranged shortly. (Author)
