THREE-QUARTER BRIDGE POWER CONVERTERS FOR WIRELESS POWER TRANSFER APPLICATIONS AND OTHER APPLICATIONS
First Claim
1. A three-quarter bridge power converter comprising:
- a first switch configured to selectively couple a switch node to a higher voltage;
a second switch configured to selectively couple the switch node to a lower voltage; and
a third switch configured to selectively cause a third voltage to be provided to the switch node when the first and second switches are not coupling the switch node to the higher and lower voltages.

Abstract
A three-quarter bridge power converter includes a first switch configured to selectively couple a switch node to a higher voltage. The power converter also includes a second switch configured to selectively couple the switch node to a lower voltage. The power converter further includes a third switch configured to selectively cause a third voltage to be provided to the switch node when the first and second switches are not coupling the switch node to the higher and lower voltages. The third switch may be configured to selectively couple the switch node to an energy storage or energy source, such as a capacitor. The third switch may also be configured to selectively couple an energy storage or energy source to ground, where the energy storage or energy source is coupled to the switch node.
