| The implementation of a prototype for a compact, high-voltage, battery-powered DC-DC source to be used as a capacitor charging power supply is studied. The small-volume, high-voltage, short charging time, and power required make it a very difficult task that has not been achieved before. Design of the control circuit and other sections is presented, and state-of-the-art technology is examined for all the components needed to implement a DC-DC full-bridge chopper converter with transformer circuit to satisfy these requirements. The principal limitations that prevented achieving the desired parameters were difficulties in the design of the transformer. Acceptable values of stray capacitance were not obtained. The only component that posed a serious volume constraint was the primary batteries. Current battery technology has not focused on this type of application, and, with the exception of thermal batteries (single operation devices), no other battery would provide the required power density at the desired voltage. |
