    摘要: A method and system for managing computational workload in a computerized system powered by an energy source. This invention relies first and foremost on adapting computational workload at the computerized system according to a time-varying property of the power supplied by the energy source, such that power generated at the source is optimized. A feedback mechanism is accordingly implemented which changes power available for computation, e.g., to track a more efficient energy generation efficiency point at the source.

    摘要: In a light power generation system, a control device, a control method, and a program, efficient power can be supplied. The maximum power detection unit operates a MOSFET in a power converter circuit and open-circuits both ends of a solar cell panel in the maximum power detection mode. After that, the maximum power detection unit short-circuits both ends of the solar cell panel, detects a maximum power by monitoring the output power of the solar cell panel during a period from the open state to the short-circuited state, and defines the voltage of the solar cell panel as an optimal voltage when detecting the maximum power. In a tracking operation mode, the control unit performs PWM control with respect to the MOSFET by defining the optimal voltage to be a reference signal. Operations are repeated between the maximum power detection mode and the tracking operation mode.
