Short Content: Abstract: The energy back coupling system to slows down our country energy supply and demand to have the vital role contradictory, but inverts the technology to hold the important position in the energy back coupling system, mainly introduced one kind of voltage incorporation invertor. First has carried on the system analysis to the voltage invertor, has given the single-phase voltage and the three-phase voltage two kinds incorporates invertor's ideal electric circuit model. Based on this, has designed one based on ...
