ABSTRACT:
A front end converter for interfacing prime power to a lower voltage distribution bus, e.g., Vdc, in a distributed power system has a natural droop characteristic which emulates a series resistor, but without associated losses. With this droop characteristic, converters are paralleled and share load current without any interconnecting control signals, thus avoiding any single point of failure and the need for several high-voltage isolation devices. The drooping effect also has a damping effect, resulting in a more stable power system.
