Zone rectifier as facility of increasing energy efficiency of DC drive

[摘要] This paper introduces prospects for further development of a single zone-phase rectifier aimed to research and improve it. The improvement of circuitry these zone-phase control circuits makes it possible to decrease the number of power semiconductors, to decrease commutation losses, to increase power factor, and finally, to increase efficiency. A new radial type circuit and its advantages are provided as well. The analysis results of zone-phase regulator circuit shows that the ways of improving their energy performance are oriented towards the development and improvement of new circuit design rectifiers and control principles.
