At present, the most obvious feature of all new energy vehicles is that the battery and motor drive system are used as the power source of the vehicle. For the motor controller in the motor drive system, the most extensive scheme is to use IGBT According to Citic Securities Company Limited(600030) calculation, the supply and demand of IGBT will continue to be tight in 2022, and the tight supply and demand pattern of IGBT in this round is expected to continue to the first half of 2023.
As the core device of energy conversion and transmission, the value of IGBT accounts for about 1-2% of the cost of the whole vehicle. According to the current market price of SiC MOSFET module for vehicles, the cost price difference between IGBT and SiC with the same current specification is at least one time, and the cost advantage of IGBT is obvious. In addition, as the core device of photovoltaic inverter, IGBT is widely used in series, centralized and micro photovoltaic inverter, accounting for about 12% of the cost. Industry insiders pointed out that the global IGBT market space in 2021 has been close to 55 billion yuan, and the compound growth rate in the past four years has been close to 20%. In the context of shortage, China's IGBT industry has ushered in the opportunity of acceleration, and is optimistic about IGBT manufacturers with rapid progress in the field of photovoltaic and electric vehicles and guaranteed production capacity.
According to the theme database of financial Associated Press, among the relevant listed companies:
Starpower Semiconductor Ltd(603290) in the field of photovoltaic power generation, the company uses modules and discrete devices of independent IGBT chips to start mass installation and application in mainstream photovoltaic inverter customers in China.
Wuxi Nce Power Co.Ltd(605111) low loss and high frequency IGBT Series products specially developed for photovoltaic energy storage market have passed the test on behalf of customers in many industries and received batch orders from customers. Some products of the company have been imported into relevant automotive electronics customers.
