Research On The Wave Control And Of Inverter

With the development of science and technology, the application of inverter is more and more widely, At the same time it has also asked the inverter output voltage waveform, the dynamic response speed faster, higher technical functions, only better understand inverter performance research, to better promote the development of inverter, it is a very meaningful work. Paper is to study the waveform control of three-phase inverter power supply is given priority to, also introduced related auxiliary function design.Multiple input multiple output coupling of three-phase inverter power supply system, by introducing concept of coordinate transformation and space voltage vector, three-phase system in a variety of mutual transformation between coordinate system, and introduces several aspects of the inverter output voltage waveform.In order to obtain high quality output voltage waveform control technology, through the understanding of repetitive control internal model controller, mathematical analysis illustrates the advantages and disadvantages of repetitive control. Also designed the inverter switching and impact resistance load function to ensure the quality of inverter to the load power supply and power supply security, require backup should quickly when switching inverter, and ensure that two inverter can always maintain the same phase. Through the research, this paper researches the reasons of transformer dc imbalance, and adopt the method of software anti bias to offset the dc bias of transformer, can be very good to improve the performance of the system.
