Self-adjusting switched-capacitor converter with multiple target voltages and target voltage ratios

摘要

A method for constructing a direct-current to direct current (DC-DC) converter from an input voltage to an output voltage. The DC-DC converter has multiple capacitors and multiple switches connectible the capacitors. A target voltage ratio is obtained based on the input voltage and the output voltage. The target voltage is expressed as a radix number. The radix number is spawned into a code of the target voltage ratio. The code is translated into a switched-capacitor converter (SCC) configuration including the switches and the capacitors. The code may be an extended binary representation code or a Generic Fractional Numbers code. The switched-capacitor converter (SCC) configuration is preferably modified to obtain charge balance.
