Amid the global wave of the carbon neutrality revolution and energy transition, silicon carbide (SiC) power modules, with their high-frequency, high-efficiency, and high-temperature operation characteristics, have become the core engine for electric vehicles, renewable energy, and industrial drives. As a global leader in silicon carbide technology, Wolfspeed's power modules have redefined the boundaries of power electronics technology with 99% conversion efficiency, 150 ° C junction temperature operation and kilowatt-level power density. Facing inventory adjustments brought about by production line upgrades and technological iterations, Shenzhen Mingjiada Electronics Co., Ltd. has launched a special high-price recycling plan for the entire Wolfspeed series of silicon carbide modules globally. Through military-grade performance testing, dynamic premium models, and 72-hour global settlement, it aims to help new energy enterprises revitalize high-value silent assets and jointly build a green and circular ecosystem for the silicon carbide industry.
I. Wolfspeed's Technological Peak: Three Core Values of the Silicon Carbide Revolution
The physical limit breakthrough of the efficiency revolution
Wolfspeed's silicon carbide modules adopt the fourth-generation M1H chip technology, reducing switching losses by 75% compared to traditional IGBTs (such as CAS325M12HM2), achieving a peak efficiency of 98.5% in 800V platform on-board chargers (OBCs), and shortening charging time by 30%. Its unique low-inductance package design (<5nH) suppresses the surge voltage within 50V, completely solving the switching oscillation problem in photovoltaic inverters.
2. Reliable operation genes in high-temperature environments
Continuous operation at 175℃ junction temperature: The CAS120M12BM2 module maintains an output current retention rate of over 90% in a 150℃ environment, eliminating the need for a complex liquid cooling system and reducing the heat dissipation cost of industrial frequency converters by 40%.
Automotive-grade robustness: Certified by AEC-Q101, it can withstand 1,000 temperature cycles ranging from -55 ° C to 175 ° C, with a power cycle life of up to 3 million times, ensuring 10 years of zero failure for the main drive of electric vehicles.
3. System-level integrated innovation
Half-bridge/full-bridge topology optimization: CCS020M12CM2 adopts sintering technology instead of solder, reducing thermal resistance by 60% and directly driving a 100kW motor.
Integrated NTC temperature monitoring: Real-time feedback on junction temperature changes (accuracy ±1℃), combined with intelligent algorithms to achieve dynamic derating control.
Ii. Mingjiada Recycling System: A Scientific Closed Loop from atomic-level Verification to Global Premium
1. Military-grade performance testing process
Wafer traceability verification: X-ray scanning is compared with Wolfspeed wafer microcode, and infrared thermal imaging is used to analyze the cavity rate of the sintering layer (requirement <1%).
Dynamic characteristic test: Dual-pulse platform verification of switching loss (e.g. CAS325M12HM2: Eon<5mJ@25℃), nonconforming rate <0.01%;
Extreme environmental challenge: Continuous operation for 72 hours at a junction temperature of 175 ° C, monitoring Vce saturation voltage drop drift (standard <5%).
2. Global Supply and Demand premium model
Based on real-time data of the new energy maintenance market in three continents:
The 800V platform model in short supply: CAS325M12HM2. Due to the urgent need for maintenance and repair of new energy vehicles, the premium rate has reached 35%.
Photovoltaic Gold Model: CAS120M12BM2, suitable for 1500V photovoltaic inverters, has a 28% premium.
Package integrity bonus: Unopened original modules (nitrogen sealed + desiccant) are subject to an additional 7% price increase.
3. ESG zero-carbon recycling commitment
Module-level rebirth: Modules that pass the 1,000-hour aging test enter the new energy aftermarket.
Material-level recycling: Extracting high-purity silicon carbide substrates from failed chips reduces carbon emissions by 92% compared to raw ore mining.
