Song Shiqiang said that in recent years, with the emergence of new demand for new energy vehicles, 5G base stations, photovoltaics, wind power and other markets, SiC (silicon carbide), as a typical third-generation semiconductor It has significant advantages in key parameters such as electric field strength, saturated electron drift rate, thermal conductivity, and
radiation resistance. According to Yole's forecast, by 2027, the silicon carbide power device market will grow from $1 billion in 2021 to more than $6 billion. Gallium nitride power devices are also attracting attention in DC converters and on-board chargers for electric vehicles. Yole predicts that by 2027, the electric vehicle market share of gallium nitride power devices will exceed US$227 million, with a compound growth rate of 99%. In recent years, the electric vehicle and industrial control markets have grown rapidly. Among them, high-voltage SiC MOSFETs, as the core components of electric vehicle main inverters and on-board chargers, have a huge market demand. Especially the 1200V/100A high-voltage, high-current SiC MOSFET chips and the same type of power modules used in main inverters and new energy vehicles represent the highest level of current SiC power electronic chip technology. Slkor Micro Semiconductor slkor (www. slkormicro.com) was one of the first to master the technology.
The third-generation semiconductors are more and more widely used. New energy vehicles such as Tesla, Xiaopeng, Ideal, Weilai, and BYD will all use silicon carbide. In the past few years, fast charging has been popular because of the technological progress of gallium nitride. Xiaomi, anker, and China's top technology enterprise are all selling well. This is the application of the third-generation semiconductor "gallium nitride" in the consumer market. As the global demand for energy saving and emission reduction becomes more and more urgent, the application fields of power semiconductors have moved from the traditional industrial control and 4C (communication, computer, consumer electronics, automobile) fields to new energy, new energy vehicles, rail transit, smart In many industries such as power grids and frequency conversion home appliances, the market size of the industry has shown a steady growth trend. Slkor micro-slkor has seized the opportunity of domestic substitution and developed rapidly, and the "slkor" brand has been accepted by more and more customers.
