In the photovoltaic inverter scenario, IGBT (including FS/NPT technology route) is the core power switching device, which needs to match the characteristics of photovoltaic string voltage fluctuation, wide power range output, high frequency efficiency, etc., while combining with new devices such as SiC FRD diodes to improve efficiency. 

Balancing supply and demand is a major challenge facing the renewable energy industry. The amount of electricity generated by photovoltaic modules is constrained by weather conditions. The MPPT controller will track the maximum power point of the solar panel in real time to maximize its performance. The higher the voltage, the more electricity can be output through maximum power tracking, thereby improving efficiency and effectively solving the living and industrial electricity consumption in remote areas and tourist areas that cannot be covered by conventional power grids, without generating environmental pollution. The independent power optimizer needs to operate in harsh outdoor conditions, so its compact appearance, efficient operation, and long service life are the key factors for its success.
