The load for the receiver on mobile devices using wireless charging is a battery. Regulation is needed for battery charging applications, e.g. constant voltage charging, constant current charging, and pulsed charging. For this purpose, the wireless power transfer (WPT) receiver can possess some “intelligence” to monitor the output voltage/current, adjust the behavior of the electronic circuitries and achieve a closed-loop control. Because a multilevel switched-capacitor (MSC) rectifier has output control ability, this can allow the MSC rectifier to directly charge the battery without an additional DC/DC charger on-board the device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multilevel switched-capacitor AC-DC rectifier for wireless charging with power regulation","description":"Described herein is a wireless charging system including switched capacitor (SC) rectifiers with output regulation.
