Magnachip entered the solar inverter market in 2020 by introducing the 1200V 40A IGBT (MBQ40T120QFS) and began offering the 650V 75A IGBT (MBQ75T65PEH) in 2022. Now, the Company unveils its latest 1200V 75A IGBT (MBQA75T120RFS), featuring its cutting-edge design technology and processes.

This new product, packaged in a TO-247PLUS with a wide heat spreader, improves heat dissipation as compared to the TO-247 package. Additionally, it enhances power efficiency by reducing conduction loss by over 14% compared to its previous generation. This improvement ensures stable operation even in overload conditions, thereby enhancing system reliability.

Moreover, this new IGBT product provides application design flexibility, as its performance can replace that of two 40A IGBTs. Another notable feature is the incorporation of a fast recovery anti-parallel diode, which quickly removes residual current to reduce switching losses and guarantees a maximum operating junction temperature of 175°C. Designed in accordance with the standards of the Joint Electron Device Engineering Council (JEDEC), this product is suitable for a wide range of applications requiring strict power ratings and high efficiency, including solar inverters, converters, uninterruptible power supply systems, and general-purpose inverters.

According to market research firm Omdia, the discrete IGBT and silicon-based MOSFET sectors in the renewable energy market are expected to grow at a compound annual growth rate of 15% from 2024 to 2028.

The new CXT-ICM3SA series offers optimal hardware and software integration of CISSOID’s existing line of 3-phase 1200V/340A-550A SiC MOSFET Intelligent Power Modules (IPMs) with an OLEA T222 Field Programmable Control Unit (FPCU) control board and OLEA APP INVERTER application software, supplied in partnership with Silicon Mobility. Depending on the selected ICM product, this modular core engine is capable of powering and controlling high voltage SiC traction inverters with battery voltages up to 850V, at output power in excess of 350kW, and with peak efficiency above 99%.

This unique integration facilitates the rapid development of SiC inverters by solving head-scratching EMC issues often generated due to fast-switching SiC transistors, by supporting different modulation schemes, e.g. SVPWM or DPWM, combined with dead time compensation, and by offering advanced motor control algorithms, including Field Oriented Control (FOC) and Flux Weakening management.

CISSOID further improves time-to-market by providing a complete SiC inverter reference design allowing motor bench testing of the ICM together with key peripheral elements such as current sensors, a high-performance DC-Link capacitor, and an EMI filter. Both the ICM and the reference design can be obtained from CISSOID, together with the motor control software and on-site technical support. 

Delivering leadership performance, the ICM supports the drive of high-speed motors, with no compromise on efficiency, thanks to the combination of CISSOID’s low 

losses SiC power module with the ultra-fast real-time FPCU, enabling high switching frequencies up to 50kHz. Furthermore, this application-specific processor dedicated to e-motor control, with onboard programmable hardware, accelerates the response time to critical events, off-loading the processor cores and enhancing functional safety. Both the FPCU and the control software are ISO-26262 ASIL C/D certified and AUTOSAR 4.3 compliant.
