IEEE 936-1987

New IEEE Standard - Inactive-Withdrawn. This guide applies to self-commutated electronic power converters; that is, converters in which commutation is accomplished by components within the converter. In converters using switching devices that have turn-off capability, such as transistors or gate turn-off thyristors, interruption of the current results in a voltage that commutates the current to another branch. In converters using circuit-commutated thyristors, the commutating voltages required to transfer current from one branch to another are normally supplied by capacitors. The type of power conversion may be dc to ac, dc to dc, ac to dc, or ac to ac.
