摘要： An example vehicle electrical power system includes a battery (12) operable to power a DC load of a vehicle over a DC bus (16), a capacitor (18), a multiphase AC machine (26) comprising a plurality of windings (A, B, C), and a power converter. The power converter includes a plurality of power switches (44, 46) and a controller (20). The controller (20) is configured to, in a first mode, charge the battery (12) by operating the power converter as an active rectifier; in a second mode, operate the power converter as a buck converter that decreases a voltage from the DC bus (16), and charge the capacitor (18) from the decreased voltage; and in a third mode, operate the power converter as a boost converter for the capacitor (18) that increases an output voltage of the DC bus (16), and provide the increased output voltage to the DC load. The power converter utilizes the windings when operated as the active rectifier, buck converter, and boost converter.
