Systems, methods, and apparatus for a high power factor single phase rectifier

Abstract

Systems, methods and apparatus are disclosed for broadband AC to DC conversion. In one aspect, a power conversion apparatus for providing direct current (DC) based at least in part on an alternating current is provided. The power conversion apparatus includes a first rectifier circuit configured to rectify the alternating current to a first direct current. The power conversion apparatus further includes an averaging circuit configured to average the first direct current received from the first rectifier circuit and to provide a second direct current. The power conversion apparatus further includes a second rectifier circuit configured to rectify the alternating current to a third direct current. The direct current is derived from the second direct current and the third direct current.

What is claimed is: 
     
         1 . An apparatus for wirelessly receiving power via a magnetic field generated by a transmitter to power or charge a load, the apparatus comprising:
 a receive circuit comprising a coil, the receive circuit configured to wirelessly couple power via the magnetic field, a voltage induced in the receive circuit in response to the magnetic field generating an alternating current in the receive circuit;   a first rectifier circuit electrically coupled to the receive circuit and configured to rectify the alternating current to a first direct current;   a first filter circuit electrically coupled to the first rectifier circuit and comprising an inductor and a capacitor, the first filter circuit configured to output a second direct current based on the first direct current;   a second rectifier circuit electrically coupled to the receive circuit configured to rectify the alternating current to a third direct current; and   a second filter circuit electrically coupled to outputs of the first filter circuit and the second rectifier circuit, the second filter circuit comprising an inductor and a capacitor and configured to output a fourth direct current based on the second direct current and the third direct current, the fourth direct current provided to power or charge the load.
