The Magnitude and Shape of the Commutating Voltage of a Three-Phase Two-Bridge Compensating Converter

The results of a study of the process of formation of commutating voltage in a three-phase two-bridge compensation converter are presented. The converter under study is a representative of a new generation of devices of this type. It uses a new technical solution in terms of implementing a commutating link consisting of a three-phase capacitor battery and a three-phase group of fully controlled devices (for example, IGBT). In this case, the effect of controllability of the process of recharging the capacitors of the commutating link is achieved and conditions are created for changing the commutating voltage both in magnitude and in shape. The previous generation of compensation converters did not have this capability. New properties of the new generation converter make it possible to ensure the adjustability of its energy process.
