A turbine-based energy generation system includes an electric generator and auxiliary load. A power system for the turbine-based energy generation system includes a main converter and an auxiliary converter. The main converter is operable to deliver power generated by the electric generator to a power collection system external to the turbine-based energy generation system when the main converter is coupled to the generator. The main converter is also operable to deliver power provided from the power collection system to the auxiliary converter when the main converter is decoupled from the generator. The auxiliary converter is operable to deliver power generated by the electric generator to the auxiliary load when the auxiliary converter is coupled to the generator. The auxiliary converter is also operable to deliver the power provided by the main converter from the power collection system to the auxiliary load when the auxiliary converter is decoupled from the generator.
