Huaxuan Yang Electronics: Optimization and Performance Improvement...
Power Over Ethernet (PoE) technology, as an important innovation, provides convenient and efficient power supply for our devices. This article will focus on the key power devices in PoE communication devices, namely MOS transistors, TVS transistors, and rectifier bridges, and explore how they work together to achieve excellent performance and stable operation. 1. Selection and optimization of MOSFETs: In PoE devices, MOSFETs play an important role in regulating power switches. Reasonable selection and optimization of MOSFET driver circuits are crucial for overall performance. Firstly, we need to consider the conduction resistance, leakage current, and conduction loss of MOSFETs. By using MOSFETs with low on resistance and low leakage current, power loss can be reduced and system efficiency can be improved. In addition, optimizing the driving circuit parameters appropriately, such as power supply voltage and pulse width, can also effectively improve the performance of MOSFETs.
