Abstract
This invention features a more compact and higher reliability power supply module including 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.

- 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.
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, wherein each DC/DC converter is configured as a buck converter with a switch cycled by the controller to modulate the DC/DC converter.
