Commonly used terms in the Electrical industry.
inverter
switching circuit that converts direct current to alternating current.
An inverter can be classified as a natural-commutation type or a self-commutation type. The output AC of a natural-
commutated inverter is synchronized to the AC line. This type of inverter is a thyristor rectifier in a reversed order. The output AC of a self-commutated inverter is independent, i.e., both the frequency and amplitude may be controlled. Commonly used self-commutated inverters include square-wave inverters and PWM inverters.
irreversible loss a reduction in the magnetization of a permanent magnet that can only be recovered by remagnetizing the material, usually caused by temperature extremes, reversing fields, or mechanical shock.
