An arrangement and method for controlling a microturbine. Back-to-back inverters are provided such that a second inverter provides power to the DC bus prior to achieving self-sustaining operation of the turbine, and a first converter provides power to the DC bus and optionally controls its voltage once the turbine is self-sustaining. The second inverter operates in either AC utility voltage and frequency control mode or output current control mode depending upon the needs of the application.

1. A turbogenerator/motor control arrangement for connection to an AC power grid, comprising:at least one AC generator; at least one turbine operatively connected to the generator; a first converter operatively connected to the generator; a second converter operatively connected between the first converter and an electric utility interface; and a DC bus operatively connected to the first and second converters, wherein power is supplied to the DC bus via the second converter during a first starting mode of the turbogenerator and power is supplied to the DC bus by the first converter during the second "generating" mode of the turbogenerator.
