Oscillating Power Generation; Oceanic Wave Energy; Simulation and Testing Abstract: A new kind of oscillating power generation device utilizing ocean waves has been designed and developed. The basic composition and scheme of conversion devices has been introduced, with the structure design being completed. Theoretical basis of the system has been analyzed and verified by test. Theory and test shows that the load voltage is 1.5V under the condition that the pendulum moves at a frequency of 0.5Hz. Power efficiency of the device is good, while structure reliability is high, and it possesses a roomy future.
