ABSTRACT:
A power loss protection system for use in a system having a spinning momentum wheel and connected to a power bus. The inventive system (10) isolates a protected circuit from the power bus (11) in the event of a system power loss and converts and regulates power taken from the kinetic energy stored in the spinning momentum wheel to a voltage sufficient to maintain operation of the protected circuit. In a most general sense, the inventive system includes a power loss detector (21) for detecting a power loss in the system bus and providing a first signal in response thereto and a regulator (26) for regulating the voltage derived from the momentum wheel energy to the protected circuit in response to the first signal.
