Power Semiconductors Weekly Vol. 53
Magnachip Semiconductor Corporation announced that the company has launched 11 new generation high-voltage 600V Super Junction Metal Oxide Semiconductor Field Effect Transistors (SJ MOSFETs). The company has already released product samples and plans to begin mass production of them in March 2022.
The new 2.5th generation (2.5G) 600V SJ MOSFETs were developed using new designs based on the latest process technology to improve switching functionality by more than 10% compared to previous generations. As a result, Magnachip has achieved lower switching loss and better power efficiency. For applications requiring high Electrostatic Discharge (ESD) ruggedness, a Zener diode is embedded between a gate and source in order to avoid damage to a MOSFET from an external surge or ESD.
The new product family of 600V SJ MOSFETs supports an Rds(on) (drain-source on resistance) of 190~580mOhm and comes in standard packaging formats, such as DPAK, TO-220F and TO-220SF. Therefore, these new 2.5G products can be widely used in products and applications including TVs, lighting infrastructure, fast chargers, adapters, PC power and industrial power supplies. They are also well suited for hard- and soft-switching topologies.
Magnachip has been delivering high-performance MOSFETs for the last 10 years. Cumulative shipments have now reached 2 billion units since the release of its first SJ MOSFET in 2013. Magnachip has supplied its current flagship 600V SJ MOSFETs to the world’s largest TV manufacturers and solidified its competitive edge in the SJ MOSFET market. Recently, major Korean TV manufacturers have stimulated demand by releasing premium models and demand for MOSFETs is expected to increase significantly along with the growth of premium TV market.
“With industry-proven technologies and products, Magnachip has satisfied the latest design requirements for both consumer and industrial markets,” said YJ Kim, CEO of Magnachip. “We will continue to develop cutting-edge power solutions like high-voltage SJ MOSFETs for automotive to expand our product portfolio and bring new capabilities to more applications.”
With the rapid growth of the electric vehicle market, USI (Universal Scientific Industrial) has begun to lay out the assembly and testing of power modules for major international power semiconductor suppliers in recent years. Recently, USI won the favor of several European, American, and Japanese clients. As a result, USI expects to officially mass-produce IGBT and SiC power modules for electric vehicle inverters in 2022.
According to Canalys, a research organization, 2.6 million electric vehicles were sold in the first half of 2021. Compared with the same period last year, sales have grown by 160%, far higher than the 26% growth rate of the global automobile market. The growth of the electric vehicle market has driven the demand for crucial power semiconductor components and modules. In particular, third-generation semiconductors boast high efficiency, low energy consumption, high frequency, high power, high voltage, and high-temperature resistance, all of these features can improve the fast-charging efficiency of electric vehicles. The development of electric vehicles and their components and modules complement each other, further accelerating the rise of third-generation semiconductor SiC and GaN chips and modules.
The five major systems of electric vehicles include the auto body, electricity, charging, battery, and motor power. Among these systems, power semiconductor components and modules are widely used for charging, battery management systems, and motor power. Electric vehicles need inverters to convert high-voltage DC power from the battery into AC power for the motor to drive. USI won a long-term contract for power modules from European clients in 2019. The modules are used for On-Board Chargers (OBC), the standard configuration for all electric vehicles, and plug-in hybrid electric vehicles. OBC converts AC power to DC power in order to charge the power battery, of which the power module plays a vital role in current rectification and voltage stabilization.
Aaron Chen, the AVP of Automotive Electronics BU of USI, said: “With a flexible and agile structure, USI will introduce product automation to continuously improve powertrain manufacturing and testing technology related to electric vehicles. The next 5 years will continue to grow, bringing tremendous growth to the automotive electronics business. Automobile OEMs and Tier 1 suppliers have high requirements for localized production. In response to growing transportation costs, USI has established 27 production locations worldwide across 4 continents, including Europe, the United States, Asia, and Africa, having the ability to provide customers with the most suitable localized manufacturing service solutions, quickly respond to customer needs, and enhance the value for customers.”
USI has more than 40 years of experience in automotive electronics fields. In addition to the successful efforts of the Powertrain System for vehicles, which has been recognized by European and American original equipment (OE) and Tier 1 suppliers, electric vehicle and new energy vehicle components have become important aspects of the company’s roadmap for automotive electronic products. These components are also driving factors of USI’s future growth.
Toshiba Electronics Europe GmbH established a new high-voltage laboratory in Germany. In line with the company’s shift in focus towards more power-related products, Toshiba invested this year in infrastructure and equipment such as high voltage power sources, loads and measuring equipment.
The high-voltage lab will be an integral part of Toshiba support and service activities for local European customers for power devices and solutions, specifically wide bandgap (SiC and GaN) technologies. Paired with engineering capabilities, for example, simulations of key power topologies and the design of reference models for power supply (i.e., PFC), inverter and EV charging applications customers can call on local support to optimize their systems related to efficiency and power density.
“The decision to invest comes as a result of recent growth we have seen through an increase in the diversity of applications our products are specified and application-related questions from customers. The new high-voltage lab will allow these to be addressed more rapidly in the customer’s own time zone and language,” explains Armin Derpmanns, General Manager, Semiconductor Marketing, Toshiba Electronics Europe GmbH.
The high-power facilities are compliant with German regulations such as VDE0100 and will have the capability to test and measure up to 1500V DC and 1000V AC.
It will also enhance the already established engineering capabilities for ASSPs and MCUs, adding now SiC and GaN devices, digital isolators, gate drivers, opto couplers/relays while focusing on key applications in the automotive and industrial market.
The high-voltage laboratory is in full operation since end December 2021.
Mitsubishi Electric is currently considering expanding production capacity for power semiconductors and turning its LCD panel plant in Kumamoto, Japan into a power semiconductor manufacturing facility.
As increasing numbers of countries are committed to achieving net-zero emissions in the coming decades, demand for power semiconductors, which can be used to improve energy efficiency for electric vehicles, appliances, and energy equipment, has risen. As a result, many semiconductor manufacturers are expanding their production.
According to information on its website, Mitsubishi Electric currently has three power semiconductor factories in the Japanese prefectures of Kumamoto, Fukuoka, and Hiroshima. Its Hiroshima plant was purchased from Japan based electronic product maker Sharp for JPY 20 billion (US$180 million) in 2020 and is expected to begin production of power semiconductors in the spring of 2022.
Mitsubishi Electric previously announced that it would invest JPY 130 billion on power semiconductors between 2021 to 2025, and Fuji Electric and Toshiba have similar production expansion plans. Fuji Electric has decided to transform its hard disk drive (HDD) component factory in Malaysia into a power semiconductor plant and build new 8-inch wafer production lines between 2023 and 2024, while Toshiba is expected to begin power semiconductor production in Nomi, Ishikawa in 2023.
