Abstract
A method and apparatus for providing power stably for direct current loads. A regulated transformer rectifier unit is controlled to provide regulated direct current power for the direct current loads at an output of the regulated transformer rectifier unit from alternating current power provided by an alternating current power source to an input of the regulated transformer rectifier unit. The direct current loads comprise passive direct current loads and active direct current loads comprising active switching power supplies. The direct current loads have at least one of constant power characteristics, resistive power characteristics, inductive power characteristics, and capacitive power characteristics. A source impedance at the output of the regulated transformer rectifier unit is determined based on an aggregate load impedance of the direct current loads and stability criterion.
