The output of the PI controller and the fuzzy logic controller.

	PI controller	Fuzzy logic controller
Total harmonic distortion THD; based on IEEE Std. 1547, which is much less than the maximum allowable 5%)	2.34%	0.04%
Waveform quality
(i) Active power profile	Less stable	More stable
(ii) Reference voltage and measured voltage of DC bus	High voltage spike	Low voltage spike
