Title: A Robust DC-Split-Capacitor Power Decoupling Scheme for Single-Phase Converter
Authors: Wenli Yao;Poh Chiang Loh;Yi Tang;Xiongfei Wang;Xiaobin Zhang;Frede Blaabjerg
Year: 2017
Publisher: IEEE
Abstract: Instead of bulky electrolytic capacitors, active power decoupling circuit can be introduced to a single-phase converter for diverting second harmonic ripple away from its dc source or load. One possible circuit consists of a half-bridge and two capacitors in series for forming a dc-split capacitor, instead of the usual single dc-link capacitor bank. Methods for regulating this power decoupler have earlier been developed, but almost always with equal capacitances assumed for forming the dc-split capacitor, even though it is not realistic in practice. The assumption should, hence, be evaluated more thoroughly, especially when it is shown in the paper that even a slight mismatch can render the power decoupling scheme ineffective and the IEEE 1547 standard to be breached. A more robust compensation scheme is, thus, needed for the dc-split capacitor circuit, as proposed and tested experimentally in the paper.
