What typically will a constant voltage CP rectifier NOT have?

A constant voltage CP rectifier is designed to convert alternating current (AC) into direct current (DC) while maintaining a steady output voltage for cathodic protection applications. The essential components of these systems typically include transformers for voltage adjustment, rectifying diodes for converting AC to DC, and adjustable outputs to fine-tune the voltage as required for specific applications.

Transistors, while useful in various electronic circuits, are not standard components in constant voltage CP rectifiers. These rectifiers primarily rely on transformers and rectifying diodes to perform their functions effectively. The absence of transistors means that the operation is more straightforward, relying on components that provide a stable and reliable output for corrosion prevention in structures like pipelines.

In summary, the lack of transistors in a constant voltage CP rectifier aligns with the design and functionality of these systems, which prioritize reliability and simplicity over the potential complexities that transistors could introduce.
