  • Publication number: 20240113501
    Abstract: An optoelectrical assembly includes a voltage conversion circuit, an optoelectrical semiconductor device, an optoelectrical detection circuit, and a controller. The voltage conversion circuit provides a bias voltage to the optoelectrical semiconductor device, and adjusts, by changing the bias voltage, an output optical power. A differential resistance value (Rdiff) of the optoelectrical semiconductor device within a range of a target optical power satisfies 0.1 ohm (?)?Rdiff?50?, and the differential resistance value is a ratio of a voltage variation to a current variation corresponding to the voltage variation. The optoelectrical detection circuit detects the output optical power, and outputs a detection signal to the controller. The controller determines a control signal based on the detection signal, and outputs the control signal to the voltage conversion circuit, where the control signal is used to adjust the bias voltage.

  • Publication number: 20230032172
    Abstract: Various examples of simultaneous ocean wave and current energy harvesting are described, using a hybrid ocean energy converter and a mechanical transfer system therefor. In one example, a hybrid ocean energy converter includes a two-body point absorber comprising a first body and a second body. The two-body point absorber can be configured to transfer a linear relative motion between the first body and the second body to bi-directional rotation of a first input shaft. A turbine can be configured rotate a second input shaft. The converter further includes a hybrid power takeoff including a mechanical transfer system configured to mechanically couple the first input shaft, the second input shaft, an output shaft, and an output shaft.
