Abstract
According to one embodiment, a power generation system includes a power generator, a displacement measuring part, and a converter. The power generator includes a movable part and converts mechanical energy of the movable part into electric power. The displacement measuring part measures a displacement of the movable part. The converter includes a switching circuit whose duty ratio is controlled based on the measured displacement, and converts a voltage level of the electric power.
Claims17
A power generation system comprising:
- a power generator that includes a movable part and a stationary part, the stationary part supporting the moving part and converting mechanical energy of the movable part into alternating-current electric power;
- a displacement measuring part that measures a displacement of the movable part;
- a controller that determines a duty ratio as a function of the measured displacement and outputs a control signal indicative of a change in the duty ratio;
- a pulse signal generating circuit that receives the control signal, generates a pulse signal with the duty ratio controlled by the controller, and outputs the pulse signal;
- a rectifying circuit that converts the alternating-current electric power output from the power generator into direct-current electric power;
- and
- a converter that includes a switching circuit whose duty ratio is controlled by the pulse signal, and that converts a voltage level of the direct-current electric power output from the rectifying circuit, the voltage-converted direct-current electric power to be supplied to an external device.
