Commonly used terms in the Electrical industry.
DC-AC inverter
See
inverter
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.
load-commutated inverter (LCI)
an inverter in which the commutating voltages are supplied by the load circuit.
single-phase inverter
an inverter with a single-phase AC voltage output. Half-bridge and full-bridge configurations are commonly used.
three-phase inverter
an inverter with a three-phase AC voltage output.
voltage fed inverter

voltage source inverter
voltage source inverter
a power converter that takes a DC voltage from a battery or the output of a rectifier and supplies a voltage of controllable and variable frequency and magnitude to a single or multiphase load.
