Technical Name A Spur-Reduction DC-DC Converter with Active Ripple Cancellation Technique
Project Operator National Taipei University of Technology, Taipei
Project Host 劉邦榮
Summary
This work presents an active ripple cancellation (ARC) technique for reducing the switching harmonics of the output voltage of a dc-dc converter. An ARC module injects an ac current to accurately cancel the inductor current ripple while the switching converter provides the dc output current. As a result, the output spur of the switching converter can be reduced effectively. However, due to the ARC
