Inventors: Steigerwald, Robert L.;
Assignee: Martin Marietta Corporation (Moorestown, NJ)
Primary Examiner: Stephan; Steven L.
Assistant Examiner: Berhane; Adolf
Attorney, Agent or Firm: Breedlove; J. M., Meise; W. H., Nieves; C. A.
A distributed power system for providing multiple output voltages, including pulsed voltages, to a solid-state phased-array radar transmit/receive module, for example, includes: an energy-storage capacitor for coupling to an input dc power source and for storing substantial energy at high voltage for supplying pulsed voltages at low voltage; at least one capacitance-multiplying converter, including first and second transformers with multiple secondary windings, for producing positive and negative voltages on buses internal to a power module; and a plurality of series regulators to obtain multiple positive and negative load voltages, including pulsed voltages, from the positive and negative bus voltages. Substantial energy storage is achieved within the power module; and, if even more energy storage is desired, an additional external energy-storage capacitor can be coupled to the input power leads, thereby being coupled in parallel with the energy-storage capacitor. Only two power pins are needed to supply the entire module. |

DETAILED DESCRIPTION A distributed power system for providing multiple output voltages, including pulsed voltages, to a solid-state phased-array radar T/R module, for example, comprises: an energy-storage capacitor for coupling to an input dc power source and for storing substantial energy at high voltage for supplying pulsed voltages at low voltage; at least one capacitance-multiplying converter, including first and second transformers with multiple secondary windings, for producing positive and negative voltages on buses internal to a power module; and a plurality of series regulators to obtain multiple positive and negative load voltages, including pulsed voltages, from the positive and negative bus voltages.
Advantageously, substantial energy storage is achieved within the power module; and, if even more energy storage is desired, an additional external energy-storage capacitor can be coupled to the input power leads, thereby being coupled in parallel with the energy-storage capacitor.
Only two power pins are needed to supply the entire module.
