ABSTRACT:
A power converter for converting an input signal having an input DC voltage level to an output signal having a desired output DC voltage level. The power converter includes a switching converter having an input which receives the input signal and a floating differential output which includes a first output and a second output. The switching converter is operative to convert the input signal to an offset voltage equal to a difference between the desired output DC voltage level and the input DC voltage level. The offset voltage is generated across the first output and the second output of the floating differential output. The input signal is applied to the second output of the floating differential output to sum the input DC voltage level with the offset voltage and thereby produce the desired output voltage level at the first output.
