− This paper analyses the influence of interference from non-ideal laboratory environment on the resistance-bridge operation. Interference can be either the result of thermal emf, electromagnetically induced voltage or harmonic distortion of the power supply voltage. Interference is manifested as the increased measurement dispersion or even as non-negligible change in the measured resistance. T...

In this paper, Vienna rectifier and Z Source Inverter (ZSI) based Wind Power Conversion System (WPCS) has been proposed with less number of switches to provide high quality power to off grid system. The three phase full bridge converter has six switches for the conversion of AC-DC and also need separate DC-DC boost converter to boost the DC voltage. In the proposed WPCS, three Phase Vienna rect...
