In accordance with certain exemplary embodiments, the present technique provides methods and apparatus for providing transient and uninterrupted power to protected loads. As one example, the present invention provides an induction device that operates as an induction motor to energize a kinetic energy storage device, such as a flywheel, during conventional operating conditions. However, in the event of a loss of primary power, the induction device, which is fed ac power at variable frequencies, begins to operate as an induction generator. For example, by varying the frequency of the input ac power such that the synchronous speed of the motor is exceeded by the rotating flywheel, the induction device acts as an induction generator and provides a transient operating power to the downstream loads until an auxiliary power source, such as a diesel generator, is brought on line.
