Research On Inverter Based On DSP For General-purpose

In the actual VVVF systems, AC variable speed control system has gradually grown into the mainstream instead of DC drive system. So far, Inverter has been widely used in all walks of industries, automatization development of production process and saves a great deal of energy and accelerates the improvement of technology. So it with great realistic significance to launch researches on inverter and technologies related to it.Constant Proportion of Voltage to Frequency is the most widely used ways in all inverter, inverter using this way cost less and control simply. This paper integrates the most lately research results on the inverter system and, on this basis, launches some theoretical study and practical application. Generally, the paper including five parts with details as following:Predominance of the frequency control system are summarized in the first part of the paper, at the same time, the paper also views the history and development trend of the inverters, finally the actuality of the domestic and overseas is reviewed.In the second part, topology and elements are analyzed first. Then the paper views the functions of the inverter, energy auto-save function is analyzed in particular.Third part, the paper studies the SVPWM technology and general analysis to the result of the matlab emulator to VVVF. The paper launches the emulator to inverter starts without loads and with pump load and sudden load.The fourth part is the detailed instructions to the hardware and software of the systemFifth part , the paper details the current waveform, and launches theoretical study .
