    Efficient Energy Technology Selects EPC’s EPC2204 eGaN for SolMate

    3 Min Read

    Efficient Energy Technology GmbH (EET), the Austrian-based pioneer in designing and producing innovative balcony power plants, has selected Efficient Power Conversion Corporation’s (EPC) EPC2204 enhancement-mode gallium nitride (eGaN®) power transistor for its latest SolMate® green solar balcony product.

    The EPC2204 strikes an optimal compromise between low RDS(on) and low COSS, critical for demanding hard switching application, while featuring a drain-source breakdown voltage of 100 V in a compact package. This compact design significantly reduces PCB size, keeps current loops small, and minimizes electromagnetic interference (EMI) emissions.

    EET has realized multiple benefits following the integration of GaN in its SolMate MPPT charging converter.  Efficiency loss has been halved, increasing overall efficiency from 96% to 98%.  The converter’s volume has decreased by 70%, the BOM and manufacturing costs have been reduced by 20%, all while lowering cooling requirements. Additionally, the increased switching frequency by a factor of 10 eliminates the need for error-prone electrolytic capacitors, thus increasing the converter’s lifespan.

    By reducing power loss, EET’s system can more efficiently convert solar energy, allowing the company to generate several megawatts of additional green solar power that would otherwise dissipate as heat on a large scale.  The reduced cooling requirements are particularly significant in scenarios without access to fresh air, where a water-resistant case is employed.

    EET’s SolMate has won many awards for its technical innovation, for the high technical standards and the innovative design, including the James Dyson Award, Living Standards Austria, the German Sustainability Award (Design), the SolarPower Summit Award, and a finalist in the Intersolar EES Award.

    Commenting on the development, Jan Senn, CMO & Sales at EET stated, “Our vision is to make renewable energy simple, safe and reliable for everyone. We accomplish this by enabling individuals to use green energy where it is most crucial – in their own homes.

    SolMate combines the highest quality, excellent user experience, and design into one user-friendly lifestyle product for every home. Transitioning to GaN helps us realize this vision, and we are currently exploring the integration of GaN transistors from EPC in other power converters as well.”

    Stefan Werkstetter, VP of EMEA Sales at EPC, stated, “We are delighted that EET has chosen our EPC2204 eGaN FET for their SolMate green solar balcony product. Our commitment to delivering high-performance and efficient power conversion solutions aligns perfectly with EET’s mission to make renewable energy accessible and reliable for all. We look forward to continuing our partnership with EET and contributing to the advancement of sustainable energy solutions.”

    2 Min Read

    Infineon Technologies AG launches its new CoolMOS™ S7T product family with an integrated temperature sensor to improve the accuracy of junction temperature sensing. The integration of these products has a positive impact on the durability, safety, and efficiency of many electronic applications. The CoolMOS S7T is best suited for solid-state relay (SSR) applications for enhanced performance and reliability due to its superior R DS(on) and the highly accurate, embedded sensor.

    Since SSRs are fundamental components in various electronic devices, customers can benefit in many ways from a superjunction MOSFET with an integrated sensor in the same package. Infineon’s innovative approach improves the relay’s performance and ensures reliable operation even under overload conditions. The integrated temperature sensor provides up to 40 percent greater accuracy and ten times faster response time than a standard independent on-board sensor located at the drain. Additionally, the monitoring process can be performed individually within a multi-device system for improved reliability.

    The CoolMOS S7T enables optimal utilization of the power transistor, resulting in enhanced performance and precise control of the output stage. Compared to electromechanical relays, the total power dissipation can be improved up to two times, while current solid state triac solutions are more than 5 times less efficient. Improved efficiency and the ability to handle higher loads help in reducing power consumption and energy costs.

    Unique output stage performance, coupled with a significant overcurrent threshold, bolster relay reliability and minimizes the risk of failure and downtime. The rugged switching solution also ensures safer operation. As a result of the MOSFETs increased robustness, the life of the relay is improved, leading to less frequent replacement. Ultimately, all of these benefits translate into lower maintenance costs.
