Challenges and Solutions in Power Modules Under Miniaturization and High-Performance Trends
Miniaturization and high performance have always been crucial trends in industrial systems and equipment, influencing the development of power modules. System manufacturers aim to provide more functions and higher performance in smaller sizes, which demands power modules to output more power within limited spaces while addressing the associated thermal challenges. Additionally, application scenarios and regulations impose new demands on power modules. For instance, power modules used in rail transportation must meet higher standards for product lifespan, reliability, vibration resistance, and EMI/EMC compatibility.
Moreover, regulatory requirements driven by global ESG policies necessitate improved energy conversion efficiency to support low-power system designs.
High Power Density Solutions That Break Space Constraints
One of the key features of the MDWI20 is its ability to achieve higher power density within the same volume. Through the adoption of advanced controllers and optimized circuit design, MINMAX Technology has significantly enhanced the power density of the MDWI20. While maintaining a footprint of just 0.94 inches x 0.54 inches x 0.4 inches, the MDWI20 increases power output from 15W to 20W, a 33.3% increase. Its power density has been raised from 74 W/in³ to 98.5 W/in³, an increase of 33%.
This optimized design provides a more powerful power output without increasing space occupation, effectively meeting the growing demand for high-performance, compact power modules and offering greater design flexibility for equipment manufacturers.
The soon-to-be-released MDWI20 power converter is only 25% the size of common products on the market, enhancing space management efficiency for enterprises and engineers.
In addition to improved power density, the MDWI20 also achieves significant breakthroughs in thermal management and energy conversion efficiency. MINMAX Technology has employed advanced thermal designs, including optimized electronic component layout and efficient thermal conduction materials, to ensure the MDWI20 maintains excellent thermal performance while delivering 20W of high power output. This innovative thermal design not only enhances product reliability but also extends its lifespan.
In terms of energy conversion efficiency, the MDWI20 utilizes a higher-grade controller, optimized electronic circuit design, layout, and more efficient power semiconductor components, significantly improving energy conversion efficiency, reducing energy loss, and minimizing overall system heat generation.
The MDWI20 boasts excellent and stable energy conversion efficiency, effectively reducing energy loss and minimizing system heat generation.
The MDWI20 also excels in reliability and durability. It features anti-sulfurization treatment technology that effectively resists the corrosion of electronic components by sulfur compounds in the environment, thereby extending product lifespan. The MDWI20 has undergone rigorous thermal cycling tests, ranging from -40°C to +125°C, withstanding 300 thermal cycles to ensure reliability and durability under extreme temperature conditions. This design enables the MDWI20 to strike a balance between high power density, high performance, and high reliability, making it particularly suitable for applications in space-constrained, poorly ventilated environments that demand high performance and reliability.
Ideal Power Solution for Rail Transportation and Broad Industrial Applications
Overall, the MDWI20 is versatile enough to cover most industrial equipment applications. Whether it's industrial automation equipment, semiconductor manufacturing equipment, CNC control systems, or injection molding machine controllers, the MDWI20 provides stable and reliable power solutions. Its unique advantages are particularly evident in the rail transportation sector, where its excellent vibration resistance and outstanding EMI/EMC capabilities make it the top choice. The MDWI20 can maintain stable operation in harsh and variable environments within onboard equipment and rail signal control systems.
Set to debut in 2025, the MDWI20 continues MINMAX Technology's legacy of excellence in industrial power modules. The company will further enhance key technologies such as thermal design, energy conversion efficiency, and interference resistance, providing customers with more advanced, efficient, and reliable power solutions, thereby expanding its competitive edge in the market.
