Nowadays, more and more devices have local area network (LAN) connectivity. To facilitate communication, the simplest solution is to power the devices via a LAN cable (Power over Ethernet), thus eliminating the need for a separate power supply.
PoE Transformer Function Introduction
A PoE power transformer is not a traditional transformer that transfers energy "in real time." Instead, it's an energy buffer and conversion hub operating in a high-frequency switching state. Through rapid switching of the switching transistors, it stores energy first and then releases it, and precisely controls the output voltage through turns ratio and duty cycle, significantly improving conversion efficiency.
Most existing systems use 2-pair output ports conforming to IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, with output powers of 15W and 30W respectively. Voohu Electronics also offers 4-pair PoE power transformers with PoEbt-compliant outputs, providing higher power output for devices.
Application Scenarios
The PoE power transformer is the core of the power management system within the powered equipment, typically located after the PD controller. Its structure and materials ensure the safe and efficient conversion of unstable high-voltage DC power from the network cable into stable low-voltage DC power required by the device or chip, greatly improving energy conversion efficiency and meeting various customer needs.
