This paper proposes the Zero Harmonic Distortion Converter (ZHD) as a master converter (MC) for medium voltage microgrids, delivering sinusoidal waveforms in both grid-connecteda nd islanded mode without sinusoidal capacitive filtering elements. The ZHD MC ensures seamless transitions between modes using a simple control approach that eliminates the need off a voltage closed-loop control for grid-connected, islanded, and transition modes, using only a current closed-loop control for grid-connected operation. Simulation and hardware-in-the-loop results show the performance of the ZHD MC converter.
