1. A method of switching between first and second voltage sources, comprising:

  • disconnecting the first voltage source from a load;

    computing volt-second areas under voltage waveforms of the first and second voltage sources in real time;

    determining a switching time to minimize downstream saturation current based on the real-time computation of the volt-second areas; and

    connecting the second voltage source to the load at the determined switching time.
