Definition of electronic transformer
Electronic transformer (Power Electronic Transformer, PET) is also called electronic power transformer (Electronic Power Transformer EPT (Solid State), solid state transformer Transformer, SST transformer (Flexible) and flexible Transformer, FT), is a new type of electric power transformer power transmission and transform technology through energy. Analyzing and summarizing the existing topological structure of power electronic transformer, can make the following definition of power electronic transformer: the power electronic transformer is a kind of power electronic technology and high frequency electromagnetic induction principle can transform technology based implementation of a power characteristic of electrical energy is transformed into static electricity equipment other a power characteristic of electric power. The power characteristics of the electric energy is mainly refers to the voltage (or current) amplitude, frequency, phase, phase number, phase sequence and waveform, etc..
