Communication Base Station Monitoring Power Module Rectifier

What is a telecom base transceiver station (BTS) rectifier system?

FTL offers a comprehensive rectifier system solution specifically designed for Telecom Base Transceiver Station (BTS) applications. Our rectifier system plays a critical role in converting alternating current (AC) power from the electrical grid into the direct current (DC) power required to operate the BTS equipment seamlessly.

What is a telecom rectifier?

According to a paper uploaded on Research Gate, typical telecom rectifiers consist of a rectifier stage (AC-to-DC converter), a DC-to-DC converter, and a battery backup system. The AC to DC converter (rectifier) usually has an input of 220V AC or 380V AC (in a three-phase five wire system), and converts that to its respective voltage in DC power.

What is a boost stage in a telecom rectifier?

The boost stage often exists in the anatomy of a telecom rectifier as a byproduct of active power factor correction (PFC). Power factor needs to be corrected because there are typically reactive power losses along cables that result in voltage drop. For example, a power factor of .9 would mean that 10% of consumed power was lost to reactive power.

Why do we need a Class 4 Telecom rectifier?

Thus, using Class 4 telecom rectifiers in telecom infrastructure would reduce cabling costs, improve safety, and reduce voltage drop along cables, while still providing the DC power necessary to power telecom equipment. Rectifiers are also applied in telecom infrastructure when small cells are being powered.

Where is a rectifier located?

Rectifiers are usually located at the base of towers (at cellular base stations) because they are typically heavy and clunky. In order to power macrocells on top of tall cell towers, long lengths of cables are used.

What is the efficiency rating of a telecom rectifier?

The efficiency rating for telecom rectifiers can usually be pretty high. Unipower and Huawei, for example, provide equipment with an efficiency of up to 96%. This equipment only loses about 4% power that passes through the rectifier as it converts AC to DC power.
