INVERTER FOR INDUCTIVE POWER TRANSMITTER

摘要

A push-pull inverter for an inductive power transmitter including a DC power supply that supplies power to a first and second branches; a resonant inductor connected between a first node on the first branch and a second node on the second branch; a first switch, switched by a first switching signal, connected between the first node and a common ground; and a second switch, switched by a second switching signal, connected between the second node and the common ground. The first switching signal is based upon the second node when the second node is low and based upon a DC source when the second node is high. The second switching signal is based upon the first node when the first node is low and based upon a DC source when the first node is high.
