Hybrid space vector modulation for low‐order common‐mode voltage reduction in current‐source rectifier for transformerless medium voltage drives

IET Power Electronics, 2023
For transformerless current‐fed medium voltage drives, low‐order harmonics of common‐mode voltages (CMVs) are more concerned with than peak values. To mitigate low‐order harmonics, the average values of CMVs should be suppressed.
