The SiC era for all is coming, are your solutions ready?
The battlefield for new energy vehicles has shifted from battery life anxiety to efficiency competition. When the 800V high-voltage platform became the standard choice for mainstream car companies, and when "flash charge in 5 minutes, 400 kilometers of range" changed from a marketing slogan to an engineering indicator, a power device revolution with silicon carbide (SiC) as the core has quietly rewritten the technical foundation of the entire electric drive and charging system.
Data confirms this trend: the SiC main drive penetration rate of new energy vehicles has exceeded 30% for the first time, the SiC penetration rate of string inverters above 200kW in the photovoltaic field has exceeded 60%, and the 800V DC architecture of data centers has simultaneously driven the demand for SiC to continue to rise. Domestic SiC, from modules to power MOSFETs, has gradually completed its goal of being put on the market. The accelerated implementation of local manufacturers is driving the penetration rate into a new round of jump.
How can SiC reshape the power structure of new energy cars?
The logic of choosing SiC is clear and pragmatic for the company and Engineer Tier1:
The electric drive system that carries the SiC module reduces energy consumption by 5 per cent to 10 per cent for the vehicle as a whole and increases the range directly by about 10 per cent; under the 800V high-voltage platform, the support capacity of the SiC device for ultra-quick charging is beyond the reach of the silicon-based device. Lower switch losses mean smaller radiative systems, lighter whole vehicle weights, better system integration – each improvement is directly translated into product competitiveness.
In the OBC (car carrying charger) scenario, the synergistic application of SiC MOSFET and SiC Shortki diodes can increase the efficiency of the charge module to over 97 per cent and reduce the volume of the equivalent power by over 30 per cent, providing greater chassis design freedom for the car company.
MOT Zheng SiC All Products: Main Drive +OBC One-stop solution
As a state-level specialty new "Small Giant" power semiconductor enterprise, SIC MOSFET and SiC Shortki-Diode complete product packages were launched around the core applications of new energy vehicles, covering three key modules:
SiC MOSFET – Core Switches for Primary Resistor
Low-conductive electrical resistance and very low switch losses to maintain stable electrical properties under high frequency, high temperature conditions
· Wide condensed temperature range (–55°C to 175°C) to meet the reliability requirements of the car ' s hologram
: : Ensuring full-life reliability through rigorous AEC-Q101 vehicle certification system
• Product parameters support direct replacement for generic, Romani and Italian semiconductor peer products
SiC Shortki diode – OBC and DC-DC condensers
• Nearly zero reverse recovery charge (Qrr) to significantly reduce switch losses in high frequency current scenes
• Optimistic system-level solution for achieving OBC efficiency in line with SiC MOSFET
: : Coverage of 600 V-1200 V voltage to fit different platform architecture requirements
SiC MOSFET+Sic diode synergy programme advantages:
• Increasing the efficiency of the main retroverter to over 98 per cent, with a significant reduction in overall energy consumption
: : Significant increase in the power density of the OBC to support the light quantification design of 11kW to 22kW fast-fill modules
The package is validated by a system-level thermal simulation, providing complete reference design programme support
Why did the car company and Tier1 choose Jen-soo?
The supply chain is self-regulating, self-manufacturing, crystal round to full chain control, completely circumventing the risk of supply disruption, and providing a stable cut-off period for volume projects.
Local technical support rapid response: The MOT application engineering team can provide heat imitation reports, device-connection programmes, PCB layout recommendations and complete test data, which can be imported from sample to mass-production running side by side and significantly compress the validation cycle.
The size of 100 billion annual deliveries is guaranteed: mature, large-scale production capacity ensures price competitiveness and mass stability, and meets the stringent supply requirements of front-line cars.
Recommended model:
MOT75CL160HF, MOT75CL180D, MOT75CL180HF, MOT80CH090N, MOT80CH090HF, MOT80CH120D, MOT80CH120HF, MOT80CH180D, MOT80CH180HF, MOT06065A2, MOT10065A2
Concluding remarks
The age of "Sic" is not a prophecy, it is a reality that is landing. For each car company and Tier1 engineer, the national production SiC programme is now organized to compete for the next generation of car-type efficiency cards. If a complete selection manual, AEC-Q101 authentication report or sample application is required, the contact team for the electronic application of the Ben-Yu electronic vehicle is welcome.
