초록

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.
