[ I claim:] [1.] A starting/generating system for use with a prime mover and operable in a starting mode to start the prime mover and further operable in a generating mode to develop power for loads, comprising:a permanent magnet generator (PMG) having a motive power shaft coupled to the prime mover

[ I claim:] [1.] A starting/generating system for use with a prime mover and operable in a starting mode to start the prime mover and further operable in a generating mode to develop power for loads, comprising:a permanent magnet generator (PMG) having a motive power shaft coupled to the prime mover and further having a winding;a bidirectional power converter having first and second inputs/outputs;a DC power bus coupled to the power converter first input/output;a DC power source coupled to the DC power bus;an AC power bus coupled between the power converter second input/output and the PMG winding;an AC load coupled to the AC power bus and receiving power from the PMG during operation in the generating mode; anda converter control coupled to the power converter wherein the converter control causes the power converter to convert power delivered by the DC power source to the DC power bus into power for the PMG during operation in the starting mode and which causes the power converter to convert power developed by the PMG on the AC power bus into power for the DC power bus during operation in the generating mode.
