Mitsubishi Electric recently introduced the Smart-1 series IGBT module at the PCIM 2011 Asia Exhibition, held at the Shanghai International Convention Center from June 21st. This new product was showcased alongside its well-known V1 series IPM, highlighting Mitsubishi’s advanced inverter technology. The Smart-1 series is designed for industrial motor drives and servo systems, offering smaller size, lower losses, and higher capacity, which has been well received by industry professionals.
The Smart-1 series utilizes sixth-generation CSTBTTM silicon technology combined with automatic crimp assembly techniques. This results in reduced saturation voltage, lower power loss, and improved thermal performance, with junction temperatures reaching up to 175°C and silicon wafer operating temperatures up to 150°C. The modules come in two configurations: CIB (Converter Inverter Brake) and 6-in-1, with current ratings ranging from 15A to 50A at 1200V.
In addition to the Smart-1 series, Mitsubishi also unveiled the V1 series IPM, a low-loss, compact version suitable for high-power motors and servo drives above 15kW. The V1 series integrates optimized temperature sensors on each silicon chip, enhancing thermal protection compared to previous models. It offers voltage options of 600V and 1200V, with current ratings ranging from 200A/1200V to 800A/600V. Compared to older models like PM300DV1A120, the V1 series reduces power loss by approximately 20%.
For renewable energy applications, Mitsubishi introduced the PV-IPM, designed for solar power systems. These modules enable more compact power converters, reducing the footprint by about 30% compared to previous versions. They are available in 4, 5, and 6-unit configurations, supporting single-phase inverters and boost circuits. The PV-IPM is ideal for residential and commercial solar installations, with rated currents of 50A and 75A.
Mitsubishi also launched the New-MPD series IGBT modules, aimed at large-scale power conversion systems such as wind and solar farms. These modules use sixth-generation IGBT silicon wafers and are designed for high-current applications. The CM2500DY-24S model, with a rated current of 2,500A, is the largest industrial 2-cell IGBT module available, supporting high-capacity power generation. The design includes ample space for water cooling, improving efficiency and reliability.
These innovations demonstrate Mitsubishi Electric's commitment to advancing power electronics for a more sustainable future. Whether in industrial automation, renewable energy, or power conversion systems, their latest products offer enhanced performance, efficiency, and compactness.
