1. A solar power voltage converter system, comprising:
a solar array for generating power;
an input terminal configured to receive an input voltage signal from the solar array;
an output terminal configured to generate an output voltage signal;
a negator circuit coupled to the input terminal and configured to provide a polarity conversion of a received input voltage signal from the input terminal to generate a negative input voltage signal, wherein the negator circuit includes a flying capacitor, a pair of first switches and a pair of second switches connected in a H-bridge configuration;
a switched-capacitor converter coupled to the input terminal and the negator circuit, wherein the switched-capacitor converter includes a plurality of converter stages, wherein each stage of the plurality of converter stages includes a capacitor and an assembly of a first switch and a second switch, resulting in a plurality of first switches and a plurality of second switches;
a control unit coupled to the switched-capacitor converter configured to activate or deactivate the pair of first switches, the pair of second switches, the plurality of first switches, and the plurality of second switches; and
wherein a configuration of the negator circuit and the switched-capacitor converter results in a voltage conversion ratio between the output voltage signal and the input voltage signal.
