Switchgear and control for an electronic power converter

TO the switchgear designer whose point of view is influenced so largely by the needs of the “man who operates and maintains,” the electronic power converter presents some new and interesting opportunities. The ease with which the converter is switched into and out of service and its output is controlled presents the opportunity of providing simple and at the same time versatile controls by means of which the operator can make the fullest use of the converter, in meeting the varying demands of his system. Protective relaying of the electronic converter against system disturbances is simple since the rectifier furnishes no power to its system and the output of the inverter is limited.
