Application of Silicon Carbide in Photovoltaic Field
Photovoltaic inverter is very important for photovoltaic power generation. It not only has the function of DC to AC conversion, but also has the function of maximizing the performance of solar cells and the function of system fault protection. To sum up, there are automatic operation and shutdown function, maximum power tracking control function, anti-independent operation function (for grid-connected system), automatic voltage adjustment function (for grid-connected system), DC detection function (for grid-connected system), DC grounding detection function (for grid-connected systems), etc.
Domestic inverter manufacturers still have too few applications of new technologies and new devices. Inverters using silicon carbide as power devices have begun to be applied in large quantities. The internal resistance of silicon carbide is very small, so the efficiency can be made very high, and the switching frequency 10K can be achieved, and LC filters and bus capacitors can also be saved. Silicon carbide materials may have breakthroughs in photovoltaic inverter applications.
