Abstract
A boost DC/DC power converter is disclosed that has a low voltage source, an inductor and a switching device that forms a series loop, a diode in series with a capacitor coupled across the switching device, a voltage divider coupled across the capacitor and a pulse width modulator that is coupled to the voltage divider. The boost converter includes a first push controller coupled across the switching device to provide a first push voltage of sufficient magnitude to turn the switching device on where the low voltage source by itself is not capable of generating a voltage of sufficient magnitude to operate the switching device.
