EET SolMate solar PV storage sys designed using EPC GaN power transistors

Austrian based renewable energy power electronics maker Efficient Energy Technology choose Efficient Power Conversion Corporation’s (EPC) EPC2204 enhancement-mode gallium nitride power transistor for its latest SolMate green solar PV balcony product. Here are some more details: 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 part...
