Yushan et al., and Siwakoti et al., proposed that “the ZSVM4 resulted in the lower current ripples when compared to ZSVM2.” However, some different opinions were presented in this paper. With the space vector modulations (SVMs) strategy, the ZSVM4 results in the lower current ripples when compared to ZSVM2 in parts angle intervals. While in other intervals, the conclusion will be opposite. The maximum current ripple of ZSVM2 is lower than that of ZSVM4. Both simulations and experimental results have verified these theoretical findings.
