A detailed pulse-width modulation strategy is presented for the proposed inverter, which can generate both equal-frequency and different-frequency output voltages simultaneously. . In addition, phase-shift control can greatly reduce the ripple frequency. The proposed approach is to cut down the switching loss of power MOSFETs by half. The inverter generates three voltage levels of magnitude, 0, and −. All the switching devices are operated at a high-switching frequency, similar to the conventional FC inverter. Finally, simulations are performed in PSIM, and the waveforms are provided, which verify the functionality of the. . The proposed dual-buck inverter uses hybrid unipolar modulation and a topology that is modified from the standard full-bridge dual-buck inverter to address the common mode voltage concerns. Therefore, for applications in which the output peak ac voltage needs to be greater than the input DC voltage, an additional boost or buck–boost DC–DC converter is needed at the front end for voltage boosting.
