Specifically matched for full-bridge rectifiers and resonant tank circuits in wireless phone charging systems exported to Europe and the Balkan region.
As Serbia accelerates its digital integration within Eastern Europe, Belgrade, Novi Sad, and Niš are emerging as crucial technology clusters. With massive foreign direct investments (FDI) in automotive manufacturing, telecommunications infrastructure, and smart IoT developments, the country is witnessing an unprecedented spike in demand for premium power semiconductors and consumer electronic components.
The implementation of smart city furniture (such as solar-powered smart benches) across Serbian urban zones demands resilient, outdoor-tolerant wireless charging modules. Simultaneously, the modernization of public transit systems and automotive infotainment assemblies requires robust, high-efficiency electromagnetic components. Our enterprise grade wireless charging solutions, coupled with WINSOK MOSFETs and Cmsemicon MCUs, deliver the precise thermal management and power conversion parameters needed for Serbia's demanding climate and operational parameters.
