ABSTRACT This letter first reveals that the conventional reactive power injection structure leads to poor grid current quality and higher current stress in cascaded current‐source rectifier (CSR). Accordingly, a coordinated reactive power control architecture is proposed to address these issues while enabling both SVPWM and SVPWAM to inject reactive power into the grid during DC load supply. Experimental results highlight the limitations of traditional methods and confirm the effectiveness of the proposed approach.
