TechConnect Innovation Program

Active Rectifier Capable of Reducing Leakage of Reverse Current, and Wireless Power Reception Device Using the Same

Sungkyunkwan University Foundation for Collaborate Business Team, Kyunggido, Korea

TECHNOLOGY SUMMARY

This technology is to solve a reverse current phenomenon, which occurs in a wireless power reception device by a delay generated by an internal circuit when the active rectifier is switched, through a delay time compensation method, and thereby to maximize the efficiency.

Primary Application Area: Electronics, Sensors & Communications

Technology Development Status: Prototype

Technology Readiness Level: TRL 5

FIGURES OF MERIT

Value Proposition: This technology can be applied to all of three standards (WPC,PMA,A4WP) related to the wireless charging.When this technology is used, it is possible to secure technical competitiveness with the wireless charging reception chip.The rectifier is an IP core of the wireless charging system, and is the most important technology.
