  • Efficient energy recovery in disk drive during power loss
    Patent number: 10374528
    Abstract: A back electromotive force of a rotating motor is converted into a voltage for a load by driving, in accordance with a duty cycle, at least one switching circuit that couples the back electromotive force to a load through a rectifying circuit. An error signal is generated that is a difference between the load voltage and a reference voltage. The duty cycle is controlled as a function of the error signal to cause the load voltage to approach the reference voltage.
    Type: Grant
    Filed: September 25, 2017
    Date of Patent: August 6, 2019
    Assignee: Seagate Technology LLC
