Abstract: A high-energy efficiency active rectifier has been implemented using cascaded H-bridge converter. As multiple levels can be synthesised by the cascaded H-bridge converter, the switching frequency of the active rectifier can largely be reduced. Consequently, the switching losses will be highly decreased. Novel switching strategy and control law have also been derived for the rectifier, so that power factor correction and multiple DC outputs can both be achieved. As an illustration, a 15-level active rectifier has been implemented using only three cascaded H-bridges. Voltage regulation for each individual bridge has also been achieved. Experimental results are included to demonstrate the effectiveness of the proposed rectifier.
