USI expects to mass-produce IGBT and SiC power modules for inverters for electric vehicles in 2022

With the rapid growth of the electric vehicle market, in recent years, USI Electronics (Shanghai Stock Exchange stock code: 601231) began to lay out the assembly, production and testing of power modules that cut into the power semiconductor international manufacturers, and recently won the favor of a considerable number of European, American and Japanese customers, and is expected to officially produce IGBT and SiC power modules used in electric vehicle inverters (Inverters) in 2022.

According to a report by research firm Canalys, global electric vehicle sales in the first half of 2021 were 2.6 million units, a significant increase of 160% compared with the same period last year, and the growth rate was much higher than the 26% of the global overall automotive market. The growth of the electric vehicle market has driven the demand for key power semiconductor components and modules, among which the third generation of semiconductors has the characteristics of high efficiency and low energy consumption, high frequency, high power, high voltage, and high temperature resistance, which can enhance the fast charging efficiency of electric vehicles, and this development complements each other to accelerate the rise of the third generation of semiconductor SiC and GaN chips and modules.

There are five major systems for electric vehicles, including: body, vehicle electricity, charging, battery and motor power. Among them, power semiconductor components and modules are widely used, and the spindle is powered in charging, battery management systems and motors. The electric vehicle must convert the high-voltage direct current output from the battery into alternating current used by the motor through the inverter to drive the vehicle. INUS Hashi received a long-term order from a European customer power module in 2019 for the On-Board Charger (OBC), which is currently standard for all electric vehicles and plug-in hybrid vehicles. ObC converts the AC power supply to direct current in order to charge the power battery, in which the power module plays an important role in the whole current and voltage stabilization.

CHEN Kunjian, AVP of USI Electric Vehicle & Electric Division, pointed out that the company will continue to grow rapidly in the next five years through flexible organization, the introduction of production automation and continuous strengthening of electric vehicle-related power production and testing technologies, contributing the largest revenue increase to the automotive power business. Automotive original equipment and first-tier suppliers for local production requirements are high, in response to the high transportation costs, USI electronics currently has 27 production bases across Europe, the United States, Asia, Africa four continents, has the ability to provide customers with the most suitable local manufacturing service solutions, quick response to customer needs, enhance the value created for customers.

USI has more than 40 years of experience in the field of automotive electronics, in addition to the powertrain system (Powertrain System) has been successful, recognized by European and American automotive originals (OE) and first-tier suppliers, electric vehicles and new energy vehicle-related parts have been one of the company's important layouts for the development of automotive electronics, and will also be one of the important engines for THE FUTURE growth of USI.
