Study Findings from Central South University Broaden Understanding of Industrial Informatics (An Active Power-Decoupling Method for Single-Phase AC-DC Converters)

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Data detailed on Industrial Informatics have been presented. According to news reporting originating in Changsha, People's Republic of China, by VerticalNews journalists, research stated, "This paper presents an active topology for power decoupling in single-phase ac-dc converters, featuring the effective suppression of low-frequency power ripple which is an inherent problem in single-phase energy conversion systems. This topology is composed of an H-bridge circuit and a ripple power-decoupling circuit."

The news reporters obtained a quote from the research from Central South University, "The ripple power-decoupling circuit shares one bridge arm with the H-bridge circuit so it has less additional components: just one IGBT, one diode, and an energy-storage inductor. Its modulation strategy is properly devised to coordinate the operation of decoupling circuit and H-bridge circuit. To enhance the power-decoupling performance, a direct ripple power-cancellation method based on energy-storage inductor is proposed. A multiresonant controller with feed-forward control is introduced for fast and precise current tracking."

According to the news reporters, the research concluded: "The effectiveness of this topology has been verified by detailed simulation studies as well as the laboratory prototype experiment results."
