A power supply system for providing long and short term backup power to a load comprises a microturbine system, a flywheel system, and a power electronics module. The microturbine system includes a microturbine attached to a first, high speed motor-generator that includes a first stator, and the flywheel system includes a flywheel attached to a second motor-generator. The microturbine system is started by a direct connection of a high frequency AC voltage output of the flywheel system (in the range of from about 500 Hz to about 2 kHz) to the stator of the first motor-generator. The direct connection of the high frequency AC voltage to the stator involves no intervening electronics.
