A power converter can be implemented with a boosted-output inverter, which integrates the functionality of a voltage converter (e.g., boost converter) and a voltage inverter. In particular, a boosted-output inverter includes a primary tank inductor coupled in series with a secondary tank inductor at a central node. The boosted-output inverter also includes two voltage-controlled switches that respectively define a charging phase and a discharging phase of the primary tank inductor. While the primary tank inductor is charging, the secondary tank inductor is inverted to ground. In this manner, current though the secondary tank inductor alternates at a voltage boosted by the fly-back voltage of the primary tank inductor exhibited when the primary tank inductor transitions from the charging mode to the discharging mode. In many cases, the secondary tank inductor is a transmit coil of a transmitter of a wireless power transfer system.
