Rectifier
A rectifier is a key piece of equipment that converts alternating current (AC) electricity into direct current (DC) electricity. Think of it like a translator that changes one type of electrical power into another that batteries and many electronic devices need. In energy storage jobs, rectifiers are important because they help charge batteries, power backup systems, and keep industrial equipment running. You might see this term in job descriptions for positions dealing with energy systems, battery technology, or power conversion equipment.
