Communication switches and routers

Communication Switches and Routers

Modern communication switches and routers are at the core of enterprise and data communication networks, enabling fast data transmission and stable interconnection. With the growth of 5G, cloud computing, and IoT, their power architectures require higher efficiency, lower loss, and compact design.

Power Architecture and Challenges

• High Density Power Conversion: Multi-phase DC-DC converters supply CPUs, ASICs, and network processors inside switches/routers. These require low conduction loss and fast-switching devices.

• 24/7 Reliability: Network equipment operates continuously, demanding high-temperature robustness and long service life from power components.

• Energy Efficiency: Reducing power loss is critical to meet energy-saving standards and reduce heat generation in compact enclosures.

Application of Power Devices

• MOSFETs (Super-Junction & Low-Voltage): Used in primary-side AC-DC conversion and synchronous rectification of power modules, delivering high efficiency at high switching frequencies.

• SiC MOSFETs: Applied in high-power PoE (Power over Ethernet) switches or backbone routers requiring higher voltage handling, enabling lower switching loss and higher thermal performance.

• IGBT Modules: Suitable for high-power backup systems or power conditioning units within large communication base stations.

• Power Modules: Integrated solutions reduce PCB area and improve reliability for compact switch/router power supplies.
