Abstract:
1. A voltage converter for use with an AC source and a DC source and for providing a DC output from the AC source and the DC source, the converter comprising: a DC input configured to be coupled to a first pole of the DC source; an AC input configured to be coupled to a first pole of the AC source; a DC output; a coil; a switching mechanism coupled to the coil, to the DC input and to the AC input and configured to selectively couple the DC input to the coil based upon a phase of a signal at the AC input and to selectively couple the AC input to the coil based upon a phase of a signal at the AC input such that the DC source is coupled to the coil if the phase of the signal at the AC input has a first polarity and the AC input is coupled to the coil if the phase of the signal at the AC input has a second polarity opposite of the first polarity; and a signal director coupled to an output of the coil and to the DC output and configured to selectively direct a signal at the output of the coil to the DC output based upon a voltage level at the DC output.
