The study introduces working principle of a multiple stage power converter, and the focus is the design of its main cir- cuit and drive circuit. The power converter achieves transformation from single - phase voltage to three - phase voltage, and it has continuous adjustable output voltage and frequency. The circuit contains several power electronic circuit links , and it has some advantages such as small volume and light weight . The paper show experimental results and waveforms of the power converter. The power converter can serve as experimental teaching and subject research platform for control field of power electronic technol- ogy and motor drive control.
