Improved Quasi-Square-Wave Modulation Suitable for Isolated Modular Multilevel DC-DC Converter

The most commonly used modulation for an isolated modular multilevel DC-DC converter (IMMDCC) is quasi-square-wave modulation (QSWM). However, in order to realize soft-switching, QSWM-IMMDCC usually needs to increase the phase-shifting angle or reduce the voltage amplitude ratio, which will not only...
