rectifier

This term belongs to the technical domain of electrical engineering. It describes a component that forces current to flow in only one direction, effectively straightening the oscillating wave of AC power into a steady stream of DC power. It is a functional term rather than a descriptive one, focusing on the result of the process (rectification). In a non-technical or figurative sense, the word is rarely used, but when it appears, it suggests a corrective force or a person who fixes a systemic error. However, in 99 percent of professional contexts, it refers specifically to diodes or circuitry in power converters.
