The Performance of a Converter with Anode Reactance

An analysis of the performance of a converter possessing both common (primary) and anode (seondary) reactance is presented. Anode reactors are invariably used in HVDC converter stations and in industrial conversion equipment employing thyristors. It is shown that if the commutating reactance is split in such a manner, the behavior of the converter is more complex compared to the case in which all the commutating reactance is common. The various modes of operation and the boundary parameters between modes are derived, and overall regulation characteristics are shown. Controlled and uncontrolled rectification as well as inversion at constant extinction angle is discussed.
