In the countryside of China, the main power supply mode is 220V single-phase power, which affects the widely application of three-phase agricultural appliances. What’s more, it means a block to the development of modern agriculture. However, frequency converter technique research is focused on three-phase high power frequency conversion technology at present, and there are very few achievements on the agricultural low power single-phrase frequency conversion research. In this paper, considering the difficulty of widely application of agricultural low power three-phase AC motor because it is not easy to obtain the three-phase power supply, a three-phase AC frequency conversion system under the condition of agricultural 220V single-phase AC power is designed, which can achieve the stepless regulation of the voltage amplitude and guarantee the widely use of the three-phase AC motor under the condition of agricultural 220V singlephase AC power. The experimental results show that the system can output the controlled three-phase AC power when the input is 220V single-phase AC power. And the rational design of the system hardware also provides the technical support for the application of agricultural low power frequency conversion.
