  • Patent number: 6469476
    Abstract: An improved motor vehicle electrical system includes a flexible topology DC-to-DC converter for coupling an engine-driven alternator to vehicle electrical loads at a mode-dependent transfer ratio. The output voltage of the alternator is regulated based the load voltage, and the converter is operable in one of a number of different modes based on engine speed, including a forward boost mode, a forward unity mode, and a forward buck mode. In the forward boost mode, the converter output voltage is boosted above that of the alternator to enable battery charging at low engine speeds; in the forward unity mode, the alternator output voltage is transferred to the battery and electrical loads at a unity transfer ratio; and in the forward buck mode, the converter output voltage is reduced below that of the alternator to enhance the alternator power output at medium-to-high engine speeds.
