Wind power generation is a renewable energy technology that converts wind energy into electrical energy. Its background can be traced back to ancient times, when people used wind power to drive sailboats, windmills, and other mechanical work. Modern wind power generation originated from the energy crisis of the late 20th century and the rise of environmental awareness. As dependence on traditional fossil fuels and concerns about global greenhouse gas emissions grew, wind power gradually gained attention as a clean and renewable energy option. Wind power generation mainly uses wind turbines to generate electricity, producing AC power at variable frequencies. However, such variablefrequency AC power does not meet grid connection requirements and must undergo ACDCAC frequency conversion to achieve safe grid integration. Achieving both types of grid connection requirements requires power conversion devices.
