The Application of Power Electronic Switch in the Regulated Capacity Transformer

The seasonal loads of rural, industrial, and mining enterprises vary sharply and their average load rate is at a low level. The replacement of the normal transformers by the ones able to regulate the power capacity and voltage can significantly reduce the no-load loss and the waste of electric energy. First, this paper analyzed the theory of the capacity and voltage regulating transformer (CVRT). Secondly, a simulation model is established by Simulink toolbox in Matlab to investigate the reduction of the impact of the current and voltage after the application of delay conduction.
