Abstract​This solution proposes an innovative high-efficiency wind-solar hybrid power generation system. Addressing core shortcomings in existing technologies—such as low energy utilization, short battery lifespan, and poor system stability—the system employs fully digitally controlled buck-boost DC/DC converters, interleaved parallel technology, and an intelligent three-stage charging algorithm. This enables Maximum Power Point Tracking (MPPT) over a wider range of wind speeds and s

Introduction and Background​​1.1 Challenges of Single-Source Power Generation Systems​Traditional standalone photovoltaic (PV) or wind power generation systems have inherent drawbacks. PV power generation is affected by diurnal cycles and weather conditions, while wind power generation relies on unstable wind resources, leading to significant fluctuations in power output. To ensure a continuous power supply, large-capacity battery banks are necessary for energy storage and balance. However, bat
