The Creativity Of Rom Is Very Eye -Catching On The Traction Inverter With A Full SIC Module

Looking back at the development of electric vehicles, early its core components mainly relied on silicon -based devices.But in recent years, withThe continuous innovation of SIC technology and the continuous improvement of cost -effectiveness, its applications have expanded from flagship models to more low -end low -voltage platforms.After 2021, the current value used by the traction inverter in pure electric vehicles is 73%between 300A and 600A, of which large currents above 300A and high -resistant regions above 400V need to use a full SIC module.Among the various SIC devices of electric vehicles, the total SIC module accounted for over 90%, mainly used in traction inverters.

Direction inverter for the host, satisfyThe full SIC module with large currents above 300A and high -pressure areas above 400V occupies an important position in the market.However, Rom, who has long been concerned about the electric vehicle field, has been lacking competitive products before.However, it shouldThe company has successfully developed in the near futureTrcdrive Pack ™, a full SIC module of electric vehicles below 300KW.According to Su Yongjin, a senior manager of the Technology Center of Roms Semiconductor (Shenzhen) Co., Ltd., TRCDRIVE PACK ™ is Rom's registered trademark. The TRC represents traction and drive.

Electric vehicle power systemMain reasonOBC, DC-DC, and driver unit (including traction inverters, motors, etc.).The driving unit can be roughly divided into three -in -one, separate electrical control, and multi -in -one types.The core of the electric drive is power devices, such as IGBT and SIC, and they are responsible for driving motors.Because the motor is usually designed to be three phases, six bridge arms are required in practical applications.In the electronic control design, most manufacturers will choose to integrate two MOSFETs of one of the bridge arms in one module to form a two -in -one module, and there are also six -in -one design that integrates all six MOSFETs in one module.Trcdrive Pack ™ is designed with a two -in -one module.In addition, the current SIC module is mainly divided into two types: glue and plastic seal. The TRCDRIVE PACK ™ belongs to the plastic seal module.

Innovative design

Always,SIC power devices are facing difficulties that are difficult to reduce size and reduce losses at the same time.TRCDRIVE PACK ™ successfully achieved the dual targets of dimensional reduction and loss of loss by using Rom's first Press Fit Pin and plastic seal module process.The module has made the top signal pin smaller, optimizing the tolerance, and the module size has reduced by 28%compared to the traditional structure.At the same time, because the signal pin is located at the top of the module, the connection can be completed by pressing the grille drive circuit board from the top to help reduce the installation time.In addition, a good balance path is designed inside the module to achieve the separation of the main current and the control signal.

The TRCDRIVE PACK ™ module has high power density characteristics, and power density is about 1.5 times that of traditional products.Under the same area, ordinary products output 300A current, while TRCDRIVE PACK can output a 450A current, which greatly improves the capacity of electromechanical control outflow.This module expands the current path in the main current wiring by using CU CLIP wiring and unique 3D CLIP design, reducing the inductance value (5.7NH), thereby reducing the switching loss.At the same time, the power terminal of the module is also optimized, which is more suitable for the actual application needs of customers.In addition, the product uses high temperature and high -performance resin to effectively solve the high temperature problem facing customers.

Roms alreadyThe TRCDRIVE PACK ™ module establishes a mass production system similar to a separate product. Compared with the previous ordinary SIC case module, the production capacity has increased by about 30 times.Due to the use of plastic seal design, the production process is simpler, and from the perspective of cost control and mass production, it has significant advantages.

TRCDRIVE pack™Cover the two -resistant level (750V and 1200V) and the size of the size to meet different power needs.Small modules are suitable for ordinary cars, while large modules are suitable for models that require higher output power, such as supercar and SUV, and its output current can reach more than 700A.This module is connected with a silver sintering processThe bottom heat sink to reduce thermal resistance, improve outflow capacity, and the entire machine heat dissipation performance.In order to meet the needs of different customers, Rom provides a wealth of product lineups.In addition, in order to facilitate customer assessment and early research and development, Rom also launchedTRCDRIVE PACK ™ andEvaluation kit of the driver board.The driver board uses Rom's own high -performance magnetic isolation driver chips, and the water channel and capacitors are specially customized and designed compactly to provide customers with great preliminary research convenience.This evaluation kit is scheduled to be launched in the third quarter.

Market goal

The electric vehicle market has always been from RomThe application market of SIC business, in the field of electric vehicles, except SIC powerFor device, Rom is also committed to providing surrounding supporting devices, such as for drivingSIC's isolation gate driver IC, power management IC, and resistance of current detection, dioma pipes, etc.It is responsible for driving SIC MOSFET's isolation meter driver IC IC using Rom's magnetic core transformer isolation technology, and integrates power supply, temperature monitoring, and protection circuits, showing its deep accumulation in the field of simulation devices.

At present, Roms ranks first in the global quarantine inverter's isolation grille drive market.+Capacity isolation gate drivers global markets account for 60%of the global market.With the construction of new factories in the Malaysian factory and expected production in the year, Rom will meet more shipments.

at present,Trcdrive Pack ™ has 4 products, including 2 models of 750V (BSTXXXD08P4A1x4) and 2 models of 1200V (BSTXXXD12P4A1x1).Rom plans to develop a total of 12 products with different 12 products in 2024 and the Small / Large and Tim: Heat Dissipation Sheet / Ag Sinter.In addition, Romom is currently developing the Six -in -One SIC packaging module products. In order to transform the product performance, the waterway, heat dissipation board, capacitance and other components have been redesigned. Based on the module form of the PIN to PIN, its power density can reach the original.About 1.3 times.

It is worth noting,The TRCDRIVE PACK ™ module is the product of Rom's latest ECOSIC ™ brand.The name of the Ecosic ™ brand is composed of two parts: ECO means environmental protection, ecology, and emphasizing the brand's environmental concept; while SIC, as one of Romm's key development strategic products, represents the brand's focus and investment in the field of SIC technology.E not only represents the earth and components, but its blue background also symbolizes Rom's pursuit of future technological innovation and a firm commitment to environmental protection.In particular, the points on the I in its SIC are designed as hexagonal, which echo the hexagonal structure of the current mainstream 6HSIC SIC devices, reflecting the close combination of brands and technology.

Rom expectThe Ecosic ™ brand can lead SIC technology in the direction of more innovative, environmental protection and ecology.In terms of product research and development and product strategy, Rom has invested a lot of resources, and the total PIPELINE has reached 1 trillion yen.Based on market demand, product competitiveness, and the number of specific orders that have been obtained, Rom set a clear sales business goal: it is planned to achieve 110 billion yen sales in the SIC sector in the 2025 fiscal year, and it will be increased to the fiscal year 2027 to the 2027th year to fiscal year to220 billion yen.At present, statistics have gained more than 130 design-win globally by all projects in 2027.
