截至目前，在光伏逆變器領(lǐng)域中英飛凌、富士電機(jī)、三菱電機(jī)、安森美、陽(yáng)光電源等一眾企業(yè)就碳化硅的應(yīng)用已經(jīng)進(jìn)行了深入的布局，并成功開(kāi)發(fā)出了量產(chǎn)產(chǎn)品。

According to statistics, by the third quarter of 2021, the cumulative installed capacity of photovoltaic generators in China reached 275GW, a year-on-year growth of 25%, and the cumulative new installed capacity of 22GW, a year-on-year growth of 45%.   In the 14th Five-Year plan, it is clearly pointed out that the installation of photovoltaic power system in China is expected to exceed 400GW by 2025.  

Now the photovoltaic industry has entered a rapid growth stage, and has brought tens of billions of market size.  Thanks to the development of the photovoltaic industry, the photovoltaic inverter, whose construction cost is nearly 20% in the photovoltaic energy storage system, has also ushered in a new opportunity for development, attracting many players to enter the fierce competition in the circuit of photovoltaic energy storage inverter.  

From the perspective of industry development and energy utilization, silicon carbide photovoltaic inverter is expected to replace the traditional silicon based photovoltaic inverter, and become the focus of industry development.   It is understood that the photovoltaic inverter using silicon carbide power devices in the system conversion efficiency can be well maintained at more than 96%, and even can reach 99%, in terms of energy loss and equipment service life has also been optimized to different degrees.  According to CASA, the proportion of high efficiency and low loss silicon carbide power devices in PV inverters is expected to reach more than 85% by 2048.  

So far, in the field of photovoltaic inverter Infineon, Fuji Electric, Mitsubishi Electric, Anson, Sun Power and other enterprises have carried out in-depth layout on the application of silicon carbide, and successfully developed mass production products.
