1. An apparatus, comprising:
a rectifier circuit to convert a voltage across input nodes of the rectifier circuit to a first voltage, the rectifier circuit operable in a positive cycle and a negative cycle, the rectifier circuit comprising first switches and second switches, wherein:
in the positive cycle the first switches are to be open and the second switches are to be closed, and
in the negative cycle the second switches are to be open and the first switches are to be closed; and
a switched capacitor circuit coupled to the rectifier circuit, the switched capacitor circuit to convert the first voltage to a second voltage, the switched capacitor circuit comprising:
a plurality of third switches to be coupled to a first set of capacitors; and
a plurality of fourth switches to be coupled to a second set of capacitors.
