Abstract:
A method of controlling a permanent magnet turbogenerator/motor comprising the steps of:providing utility electrical power to the permanent magnet turbogenerator/motor through a pulse width modulated inverter to start the permanent magnet turbogenerator/motor to achieve self-sustaining operation of the permanent magnet turbogenerator/motor;disconnecting the utility electrical power from the pulse width modulated inverter once self sustaining operation of the permanent magnet turbogenerator/motor is achieved;reconfiguring the pulse width modulated inverter to supply voltage from the permanent magnet turbogenerator/motor; andproviding an energy storage and discharge system for the pulse width modulated inverter to provide electrical energy to the inverter when utility electrical power is unavailable to start the permanent magnet turbogenerator/motor and during self-sustained operation when the inverter cannot meet an instantaneous load requirement and to otherwise store electrical energy during self-sustained operation.
