Abstract

The invention relates to a self-started and self-powered energy collecting circuit for ocean energy generation. A self-powered circuit is a structure in which a serial connected structure of a diode and an energy-storage capacitor is in parallel connection with the part between drain-source electrodes of a power switching tube in a traditional BUCK structure circuit, and electric power in the capacitor is provided for a self-started circuit; the self-started circuit is used for driving the power switching tube; a self-powered energy collecting circuit comprises a rectification circuit, the self-powered circuit and an energy management controlling device; the energy management controlling device is used for conducting charge-discharge management on an energy storage device and conducting communication with the self-started circuit through a photocoupling manner. According to the energy collecting circuit, the energy collecting circuit is suitable for the application of a small ocean energy independent power generation system, and the energy collecting circuit has the advantages of generator starting under a low energy condition, electric energy self collecting, system power generating and storing capacity increasing and the like.

Description

technical field [0001] The invention relates to a self-starting and self-powered energy collection circuit for ocean current energy and wave energy power generation. Background technique [0002] The ocean accounts for about 71% of the earth's surface area, and has abundant ocean energy resources, such as tidal energy, tidal current energy, wave energy, ocean temperature difference energy, salinity difference energy and offshore wind energy. As a renewable energy source, ocean energy has been more and more researched, developed and applied. At present, the most common form of ocean energy utilization is ocean energy power generation, and there are already some ocean energy power stations that have been successfully commercialized. For some islands or marine instruments that need power supply far from the coastline, ocean energy resources can be used to generate electricity according to local conditions to solve their power supply problems. For these special users, miniaturi...
