As the global energy crisis continues to intensify, solar energy as a green and renewable energy source is gradually attracting people's attention. In solar power generation systems, photovoltaic inverters play an indispensable role as they can convert the direct current generated by solar panels into alternating current for household appliances. Used for feedback back to commercial transmission systems or for use in off grid power grids. With the continuous improvement of power levels and the increase in overall size, photovoltaic inverters have increasingly high requirements for the specifications and heat dissipation of power devices. Compared to traditional silicon materials, silicon carbide has superior performance, so the use of silicon carbide power devices in photovoltaic inverters is becoming increasingly widespread.

For string photovoltaic topology circuits and micro inverter circuits, the 650V and 1200V series SIC diodes produced by Jiangsu Haisimei have conductivity and reverse recovery characteristics similar to international brands, and have excellent comprehensive surge resistance performance.
