Vector Control of Modular Multilevel Converter Based Regenerative AC to DC converter

摘要

A three phase AC to DC modular multilevel converter (MMC) with simple Phase disposition pulse width modulation is used. To control the converter d-q rotating reference frame is used. N+1 PS-PWM modulation scheme is used to limit the circulation current, where, the lower arm switching states are complementary of the upper arm switching states. The AC to DC converter is verified by simulation and results are presented.
