Power is the driving force for some electronic devices, which is a highly versatile electronic product. It has been widely used in various industries and daily life, its quality greatly affects the reliability of electronic equipments, the scope of its application depends on the conversion efficiency and the strength load capacity. Square-wave output inverter with high efficiency, but it’s not good for the electronics designed with sinusoidal electrical power, although many appliances can suit, but some would not, or the indicators change. There will not be such shortcomings of sine wave output in this regard for precision rectifier; but with the shortcomings of low efficiency. In this paper, based on the basic principles of the power inverter, with the analysis of available information, a sine wave inverter and debugging methods tried to be carried out.
