| 1. A compact and higher reliability power supply module comprising:
a high voltage DC input;
a low voltage DC output;
a number of DC/DC converters connected in parallel between the high voltage DC input and the low voltage DC output; and
a controller configured to modulate each DC/DC converter to convert the high voltage DC input to the low voltage DC output
by utilizing pseudo-impedance to provide load sharing with other power supply modules without direct communication with other
power supply modules and without feedback from a point of common reference.
