Rectifier

Glossary By Rickard Andersson

Definition

A rectifier is an electrical device that converts alternating current (AC) into direct current (DC). This conversion is essential for powering equipment that operates on DC voltage, such as telecom electronics, battery systems, and DC-powered cooling units.

Context

In Vikinor’s DC power and hybrid energy systems, rectifiers are a critical interface between grid power, batteries, and connected loads.

They ensure that incoming AC power is converted into clean, stable DC voltage suitable for telecom equipment, control electronics, and energy storage systems.

Rectifiers are especially important in 48V DC telecom architectures, where voltage stability and efficiency directly affect system reliability and battery performance.

Technical insight

Rectifiers operate using semiconductor components (such as diodes or controlled switching devices) to allow current to flow in one direction only.

In industrial and telecom systems, rectifiers typically include:

  • AC input stage connected to the utility grid or generator
  • DC output stage supplying loads and charging batteries
  • Control and monitoring circuitry for voltage regulation and protection
  • Redundancy (N+1 configurations) to ensure uninterrupted operation

Vikinor integrates high-efficiency rectifier modules designed for:

Efficient rectification reduces heat generation, improves system efficiency, and extends equipment lifespan.

FAQ

Telecom equipment operates on DC voltage. Rectifiers convert grid AC power into stable DC power while charging batteries and supplying loads simultaneously.

A rectifier converts AC to DC, while a power supply typically includes additional regulation, filtering, and protection functions.

Yes. In hybrid systems, rectifiers work alongside solar charge controllers to manage multiple power sources efficiently.
