An auxiliary power unit (APU) generator system (100) for an APU can include a doubly-fed induction generator (DFIG) (103) configured to be operatively connected to an APU to be turned by an APU and to have an output frequency that is a function of an excitation frequency and an APU speed. The system can include a generator control module (105) configured to control the excitation frequency to the DFIG to output a substantially constant frequency with changing APU speed to supply the substantially constant frequency to a load.
