Research On Control Of Inverter

The content of this dissertation belongs in the research fileld of power appliance technology. The performances of inverters are becoming more and more important along with the inverter technology's widely using in lots of fields as the high speed developing of the power electronics and the more need for the electrical systems on control performance in some fields. In this condition, this paper focuses on voltage regulation strategies of CVCF(Constant Voltage Constant Frequency) inverter as tradition regulation strategies' limits.Firstly, this paper make a completely research on inverters in theory and the system model is established. Then some criterions of control qualitities are got by the model and several controllers are researched in theory and simulation based on the criterions.As a advanced regulation strategies, this paper make a deeply discussion on the P+Resonant regulator. The regulator which have a instantaneous muitiple loop can achieve good transient and steady-state performance as the regulator's outer loop transfer function can be transformed insteaed of the ac error.In the end, this paper has a research on feed forward regulator in theory and experiments. As a simple digital regulation strategy it has a high quality output on linear loads and no loads. The design is to be proved is useful in lower cost and lower power situation. The system's hardware and software design which base on the DSP TMS320LF2407A are both introduced in details in the experiments.
