Abstract
A boost converter is provided for tracking change in input voltage. The boost converter comprises at least one input for connection to a DC voltage source for supplying an input voltage; at least one output configured to supply an output voltage having a value that is greater than a value of said input voltage by at least a predetermined offset value; feedback means adapted to provide a feedback voltage, based on said output voltage, to a switching element of said boost converter, and a feedback voltage regulator means adapted to combine said feedback voltage with an input voltage characteristic so as to adjust said output voltage to be offset and proportional to said input voltage characteristic.
