Study on One-phase to Three-phase Converter Based on Static Var Compensation

The technology of converting single-phase AC to three-phase AC has the prospect of wide application in electrified railways and remote mountainous districts.However,the related technical issues have not been well solved for a long time.It is of practical significance to find a single-phase to three-phase conversion technique to supply good price-performance three-phase power where it is needed.In this paper,the split-phase principle and two theoretical schemes to convert one-phase AC to three-phase AC are introduced;the working theory of TCR and TSC is introduced;according to the theory of converting single-phase AC to three-phase AC and the theory of TCR and TSC,the implementation mode of the TCR-based and TSC-based single-phase to three-phase converters is put forward.Thus,the single-phase to three-phase converter applicable to electrified railways and remote mountainous districts is formed.
