According to data, the market size of China's power devices including power ICs and power modules reached 147.35 billion yuan in 2019, and the market size in 2020 was 160.3 billion yuan, a year-on-year increase of 7.50%, making it the largest power device market in the world. It is expected that the compound growth rate of China's power device market scale will reach 7.62% in the next three years.

my country is the world's largest consumer of power devices. In the power device segment, MOSFETs account for 30% of the global market, power management ICs account for 35%, and thyristors, rectifiers, IGBT modules and other products account for 30% of the global market in China. 35% or so.

Domestic semiconductor manufacturers are IDM models with relatively complete production. Intuoku products are mainly in the fields of diodes, low-voltage MOS devices, power semiconductors, etc. The production process is mature and has advantages, and it is widely used in high-end products such as new energy and rail transit.

Infineon, the world's largest power device manufacturer, has increased its sales in China from 16% in 2018 to 25% in 2019 and 44% in 2020, further verifying the rapid development of the domestic power device market.

Domestic power semiconductor manufacturers have mature production processes, and in the high-end field, the market is still dominated by foreign companies. The development prospect of the domestic market is broad, and the realization of technological breakthroughs and product improvement is the future development direction of my country's power semiconductor industry.
