A power management system for a vehicle. The system may be flexibly configured using various arrangements of DC to AC inverters, DC to DC converters AC to DC converters, DC to AC converters and AC to AC converters, one or more batteries, and a control portion to provide an AC bus, a primary DC bus and a secondary DC bus. The control portion monitors the status of the buses, inverters and converters and controls the operation of the inverters and converters to supply and regulate the power supplied by the buses. The inverters and converters may be bidirectional, allowing power to be transferred between buses.
