Abstract
A system and method for converting power are disclosed. Briefly described, one embodiment comprises a first power source having a first-source positive terminal and a first-source negative terminal; a second power source having a second-source positive terminal and a second-source negative terminal; an output capacitor having an output-capacitor positive terminal operably coupled with the second-source positive terminal and an output-capacitor negative terminal operably coupled with the first-source negative terminal; a series electrical connection between the first-source positive terminal and the second-source negative terminal; a boost converter having a boost-converter input operably coupled with the series electrical connection and the first-source negative terminal, and a boost-converter output operably coupled with the output-capacitor positive and negative terminals; and a buck-boost converter having a buck-boost-converter input operably coupled with the series electrical connection and the second-source positive terminal, and a buck-boost-converter output operably coupled with the output-capacitor positive and negative terminals.
