| Abstract: |
| EPT (Electronic Power Transformer) is a new type of transformer,which realizes voltage trans-formation and power delivery in power system through power electronic conversion. The main principle of EPT is described and simulation of a new EPT scheme is carried out,in which its steadystate characteristic and dynamic characteristic in four conditions are involved. Simulative results show that EPT guarantees good voltage and current waveforms in both primary and secondary sides and has good control performance. It can be used as a new regulating device of power quality for its regulating function. |
