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.
Key words: three levels; VIENNA rectifier; electric quantity parameter measurement; circuit design; digital signal processor
