Abstract
According to one embodiment, a power control circuit includes a converter, a signal generating circuit, an estimation unit, and a controller. The converter includes a switching circuit and is configured to transform an output voltage from a power generator. The signal generating circuit is configured to transmit a signal to the switching circuit. The estimation unit is configured to determine a switching operation condition based on vibration information indicative of a vibration applied to the power generator. The controller is configured to control an operation of the switching circuit based on the determined switching operation condition.

A power control circuit comprising:
- a converter including a switching circuit configured to be switched ON and OFF alternately, the converter being configured to transform an output voltage from a power generator based on a switching operation of the switching circuit;
- a signal generating circuit configured to generate a signal for driving the switching circuit and apply the generated signal to the switching circuit;
- an estimation unit configured to determine a switching operation condition based on vibration information indicative of a vibration applied to the power generator and using a plurality of switching operation conditions prepared in advance, the switching operation condition and the plurality of switching operation conditions each including information for specifying a duty cycle indicating a fraction of a period in which the switching circuit is ON;
- and
- a controller configured to control the switching operation of the switching circuit based on the determined switching operation condition.
