Rectifier 整流器

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation is performed by the inverter.

整流器(英文:rectifier)是把交流电转换成直流电的装置,可用于供电装置及侦测无线电信号等。整流器可以由真空管,引燃管,固态矽半导体二极管,汞弧等制成。相反,一套把直流电转换成交流电的装置,则称为“逆变器” (inverter)。
