A microturbine power generation system includes an electric generator, a rectifier for rectifying an output of the electric generator, and an inverter for up-chopping an output of the rectifier. The inverter can also be controlled to provide an excitation current to windings of the electric generator. The excitation current causes the electric generator to operate as a motor. The electric generator can be operated as a starter motor for the system.
[ What is claimed is:] [1.] A microturbine power generating system comprising:(a) a turbine for converting gaseous heat energy into mechanical energy;(b) an electric generator including a permanent magnet rotor and stator windings, said stator windings including an electrical output, said rotor being driven by said mechanical energy from said turbine;(c) a rectifier coupled to said electrical output of the stator windings;(d) a source of dc power;(e) an inverter coupled to both said rectifier and said source, said inverter operable in both a startup mode...
