TL;DR: The proposed schemes are proven to be effective to elimination of the hybrid ZSCCs and modified LCL filters are proposed to eliminate the high-frequency and low-frequency harmonics components.

TL;DR: An optimized third harmonic compensation strategy that injects moderate amount of third harmonic into the overmodulation H-bridges to keep the amplitudes of their modulation waveforms just being unity, then compensates the same amount of opposite harmonic sequence and properly distributes it to rest of the H- bridges is proposed.

TL;DR: Simulation and experimental results validate the effectiveness and feasibility of the proposed hybrid modulation strategy and show it is capable of suppressing dc voltage fluctuation, and, thus, improving the output power of solar cells.

TL;DR: An optimized third harmonic injection method based on fundamental frequency zero sequence injection (FFZSI) is proposed, which can reduce the dc-link voltage fluctuation and extend the power balance range of FFZSI at the same time.

TL;DR: A modified phase disposition pulse width modulation for the symmetrical circuit is proposed, which can eliminate the leakage current effectively with simple implementation, and it has a little effect in the asymmetrical circuit.
