Fel un o rannau craidd y system gyfathrebu, Mae gan yr gwrthdröydd pŵer cyfathrebu safle pwysig heb ei ail yn y Peirianneg Gyfathrebu. Mae'n cynnwys ystod eang o gynnwys, including not only commonly used switching power supplies, UPS power supplies, communication batteries and diesel generator sets, but also green communication power supplies such as solar cells. The core of the communication power inverter is basically the same, which is based on power electronics. Through the stable control loop design, coupled with the necessary external monitoring, the most red realization of energy conversion and process monitoring. Modern communication equipment needs a stable and reliable power inverter to provide power.

The safety and reliability of the power supply is an important condition to ensure the normal operation of the communication system.
