1. A method of controlling a permanent magnet turbogenerator/motor comprising:

  • providing a protected load connected in parallel with the turbogenerator/motor through a pulse width modulated inverter configured in a first operating mode to supply controlled current from the turbogenerator/motor to a utility electrical power source, and selectively connected to the utility electrical power source through an isolation device;

    monitoring the utility electrical power source; and

    automatically disconnecting the protected load from the utility electrical power source by opening the isolation device and reconfiguring the pulse width modulated inverter in a second operating mode to supply controlled voltage to the protected load when a fault is detected in the utility electrical power source.
