Abstract: An apparatus, system and method for wirelessly powering a device. The apparatus, system and method may include a primary coil housing that houses a primary coil; a secondary coil housed within the device and suitable for having power induced therein responsive to the primary coil; an isolator that at least partially mechanically and electrically isolates the primary coil from the secondary coil; and a plurality of paired feedback sensors respectively communicatively and physically associated with, and paired as between, the primary coil housing and the device, wherein the plurality of paired feedback sensors exchanges indications regarding performance of the secondary coil, and wherein performance of the primary coil is modified responsively to the indications.

Abstract: A power inverter, such as a synchronous buck power inverter, that is configured with a high frequency switching control having a (PWM) controller and sensing circuit. Controller provides a low frequency oscillating wave to effect switching control on a synchronous-buck circuit portion that includes a plurality of switches to invert every half cycle of the frequency provided by controller. The inverting process thus creates a positive and negative transition of the oscillating wave signal. A low frequency switching stage includes a further plurality of switches configured to operate as zero voltage switching (ZVS) and zero current switching (ZCS) drives Charge on an output capacitor is discharged to zero on every zero crossing of low frequency switching stage and advantageously discharges energy every half cycle. During this discharge of energy, the zero crossing distortion in the low frequency sine wave is greatly reduced.
