Abstract: This study analyzes how to efficiently create a storage circuit to charge a capacitor with a radioisotope power converter. Variables analyzed include capacitance and frequency of pulse/discharge. Virtual Test Bed was used to display the transient effects of the charging circuit. MATLAB was used to explore the efficiency of circuits. Results indicate efficient circuits need a capacitance that correlates to the number of times the capacitor is discharged in a day.
