Description
technical field [0001] The invention relates to the technical field of inverters, in particular to a wind-solar hybrid full-bridge inverter and a wind-solar hybrid power generation system. Background technique [0002] In nature, solar energy and wind energy are the most common and inexhaustible renewable energy sources, and the two have strong complementarity in time variation distribution. Due to the disadvantages of wind-solar power generation such as poor stability, low energy density, and weather-affected factors, the use of wind-solar hybrid power supply systems has become a major trend. The wind-solar hybrid power supply system uses solar energy and wind energy to supply power to the load at the same time, which can maximize the use of green and renewable energy. The complementarity of the two resources makes the wind-solar hybrid power generation system have a good match in resource distribution, ensures the output of power energy, and can greatly improve the contin...
