A vehicle includes an engine, a transmission connected to the engine, an auxiliary electrical load, and an electrical system. The electrical system includes a high-voltage energy storage system (HV-ESS), an auxiliary/low-voltage energy storage system (LV-ESS) connected to the load, a full-bridge active rectifier/inverter, a semi-active auxiliary rectifier, and a motor generator unit (MGU) connected to the HV-ESS via the active rectifier/inverter, and to the LV-ESS via the semi-active auxiliary rectifier. A controller establishes a first operating mode in which the MGU is operated as a motor for restarting or assisting the engine via the active rectifier/inverter, and second operating mode in which the MGU operates as a generator and the semi-active rectifier provides an auxiliary DC output voltage to the LV-ESS and the load. Another vehicle has first and second switches in lieu of the semi-active rectifier, with the active rectifier connected to the HV-ESS and LV-ESS via different switches.
