**5. Conclusions**

In this paper, three hybrid modulation strategies were proposed. The proposed modulation strategies combine the time calculations of the space vector modulation technique and the comparison of the reference signals with a carrier triangular waveform, as does the sinusoidal pulse width modulation strategies. The results show that the SVM algorithms for the DCM-232 can be implemented using this combined method, which is convenient for practical implementation in a digital platform. Moreover, an evaluation of the efficiency was performed, and the results show that the modulation sequence has an important effect on this parameter. This analysis demonstrates that the CASVM technique has the highest efficiency (95.85%) among the proposed modulations algorithms, although all of the proposed methods present an efficiency above 85.5%. Finally, it can be also concluded that any of the proposed techniques is capable of reducing the magnitude of the common mode current (i.e., up to 140 mARMS for the CSSVM technique), which is a very interesting feature for transformerless photovoltaic applications since the power inverter operation complies with the international standards.
