This paper proposes a kind of inverter topology and control method with a capability of high-frequency,high-power sinusoidal output. Switching devices with operating frequency equal to that of the output voltage can be used in this kind of inverter. Moreover,it has a good quality of sinusoidal waveform. It is suitable for many applications such as ultrasonic precise machining,cleaning,high-power electrochemical industry,ultrasonic pollution control and so on. By experiments,the parameters about output quality and efficiency are acquired,which demonstrate that the three-level inverter scheme is practicable.
