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.
