WIRELESS POWER RECEIVER HAVING ACTIVE RECTIFIER

摘要

According to various embodiments of the present invention, an active rectifier may include: a first - a fourth MOSFET which perform a switching operation according to an input voltage from a power receiver and are connected in a cross-coupled structure; and a ZVS&ZCS controller which controls each of the third MOSFET and the fourth MOSFET to perform zero voltage switching (ZVC) or zero current switching (ZCS). Besides these, various embodiments are possible. The active rectifier has a relatively high input voltage and a relatively high operation frequency.
