Abstract

An AC-RDCL three-phase inverter topology which uses a fourth inverter-branch devoted to accomplish both the modulation of the machine neutral voltage and the converter zero-voltage switching is described. The DPM control strategy related to the inverter modes of operation is discussed, and the feasibility of the approach is shown by means of results taken from a computer simulation and an insulated gate bipolar transistor (IGBT) converter prototype
