1. A method for operating a power converter system, the method comprising:
receiving input AC power at an input from an input power source, the input power source having a peak voltage limit;
operating a charger coupled to the input to convert the input AC power into first DC power having a first voltage level;
providing the first DC power having the first voltage level to a DC bus;
operating at least one power converter coupled to the DC bus to convert DC power from the DC bus into output power and provide the output power to at least one load; and
in response to a voltage demand of the at least one load exceeding the peak voltage limit of the input power source, providing second DC power having the first voltage level to the DC bus from an auxiliary power source to supplement the first DC power provided by the charger.
