Abstract: Compared with the traditional two-level converter, the output level number of multi-level converter increases and the output waveform ladder increases, so it is more close to the target modulated waves. This paper analyzed the working principle of a threephase/level/switch (VIENNA) rectifier, discussed the implementation of the circuit, and introduced the design of the main circuit and sampling circuit in detail. An 800W experimental platform was built. TMS320F281 2 DSP was used to realize the control algorithm. Experimental results show that the designed circuit can meet the preconcerted requirements in possession of wide prospect for application of industrial control.
