Claim:
1. A power supply comprising: a controller; a first half-bridge circuit electrically connected to the controller; a second half-bridge circuit electrically connected to the controller; wherein the first half-bridge circuit is electrically connected to a first terminal of a primary coil through a first capacitor and the second half-bridge circuit is electrically connected to the first terminal of the primary coil through a second capacitor, wherein the first-half-bridge circuit lacks direct electrical connection to a second terminal of the primary coil and wherein the second half-bridge circuit lacks direct electrical connection to the second terminal of the primary coil; wherein the controller selectively configures the power supply between a plurality of different bridge topologies during operation by controlling the first half-bridge circuit and the second half-bridge circuit to adjust the resonant frequency.
