Abstract
Reducing power loss in wireless power receivers is important to avoid thermal design issues. Synchronous rectification is a suitable means for loss reduction. In this paper we propose a synchronous rectifier with a simple control scheme. A detailed analysis leads to a time-domain model which is used to perform a power loss analysis. Experimental verification shows that the predicted efficiency improvement agrees with measurement results.
