Abstract


Research papers on digital control technology for inverter power . Relative to the analog control , digital control has to simplify the hardware circuit design , to overcome the temperature drift of analog circuit parameters to control the flexible and easy to implement advanced control technology , reliable performance , and reduce development cycles , etc. , and with the new power electronic devices and digital processor the rapid development of the increasingly widespread application of digital control power inverter , and become part of the power trends . The papers on the basis of the model of the single-phase inverter power circuit to establish a mathematical model of continuous-time and discrete-time domain , and provides a theoretical basis for the control system design ; brief sinusoidal pulse width modulation principle and single bipolar sine pulse width modulation works , analysis of the harmonic content of the sinusoidal pulse width modulation . Chapter III of the article describes the digital PID technology and discrete sliding mode control technology , based on the advantages of the double loop control , the establishment of a single-phase voltage outer PI control and outer voltage discrete integral sliding mode control using MATLAB / SIMULINK simulation software inverter simulation model and simulation analysis . The fourth chapter is constructed based on the the TMS320LF2407A single phase digital control power inverter experimental platform , details the implementation of the system hardware circuit design , software programs . Finally, a test of the single-phase voltage source inverter power waveform and its analysis and experimental results show that the system has good dynamic and static performance .
