The Research and Design of 800W Inverter Based on Sino Wealth SH79F082 Single-Chip Microcontroller

This paper firstly introduces the basic characteristics of SH79F082 single-chip microcontroller and describes the domestic situation of inverter technology. Using this microcontroller, the researcher is to design an 800W inverter that is mainly used in the communication stations. Then the author describes the design of the inverter from the aspects of the main circuit and peripheral circuit. Next, combined with single-chip microcontroller and the needed function, the author analyzes software design, mainly including sampling and control program. In the end, with the oscilloscope, we detect the output-waveform to check up our design. And its various performance indicators are also tested by using the high and low temperature testing. Finally a kind of inverter with a high cost performance is developed after several times of improvements.
