摘要

This paper briefly describes direct power control methods for two- and three-level AC/DC converters and their modified DPC 3 ?— 2-?′ and the DPC 5 ?— 2-?′ algorithms. It also presents two new control methods DPC-3Am (direct power control 3 areas with modification) and the DPC-3L-3Am (direct power control 3 levels 3 areas with modification). The research results were used to compare the described methods. The comparison was based on an average value of switching frequency and current distortion coefficient. Experimental investigations into the methods have shown that the use of the modified DPC methods reduces the number of switchings by more than 70% compared with the standard DPC method.
