发明名称 Adaptive synchronous rectification of brushless DC motor back-EMF
摘要 An embodiment of a disk drive power system is described. The system is operable such that during power interruption, the system taps electric power by rectifying the back-EMF generated across each winding of a DC motor and supplying power to a voice-coil motor to park a read/write head safely away from an associated magnetic disk surface.
