Compared with the traditional two-level converter, the output level number of multi-level converter increases and the out-put waveform ladder increases, so it is more close to the target modulated waves. This paper analyzed the working principle of a three-phase/level/switch (VIENNA) rectiifer, discussed the implementation of the circuit, and introduced the design of the main circuit and sampling circuit in detail. An 800 W experimental platform was built. TMS320F2812 DSP was used to realize the control algorithm. Ex-perimental results show that the designed circuit can meet the preconcerted requirements in possession of wide prospect for application of industrial control.
